Check Digit Verification of cas no

The CAS Registry Mumber 1012341-54-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,2,3,4 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1012341-54:
(9*1)+(8*0)+(7*1)+(6*2)+(5*3)+(4*4)+(3*1)+(2*5)+(1*4)=76
76 % 10 = 6
So 1012341-54-6 is a valid CAS Registry Number.

Preparation method of sacubitril valsartan sodium

-

Page/Page column 11-14, (2021/03/31)

The invention provides a preparation method of sacubitril valsartan sodium, and belongs to the field of medical chemistry. The preparation method comprises the following steps: by using a compound S309A03 as a raw material, carrying out hydrogenation reaction to generate a compound BPA08, reacting the compound BPA08 in ethanol to generate a compound SAC01, reacting the compound SAC01 with succinicanhydride to generate a compound SAC02, optionally reacting the compound SAC02 with sodium hydroxide, and reacting the compound SAC03 with calcium chloride to generate a compound SAC04; and subjecting the compound SAC04 to acid treatment to obtain a compound YJX01, and enabling the compound YJX01 to react with VST in a single solvent in the presence of sodium hydroxide to prepare the compound YJX02. The preparation method disclosed by the invention is simple to operate, the time required by the process is reduced, the total yield of the process route is greatly improved, an unexpected technical effect is obtained, impurities in the process are removed, and a product with higher purity is obtained. The method has mild process conditions and easily available raw materials, and is suitable for industrial amplification.

Substituted ferrocenyl diphosphine homogeneous catalyst ligand

-

Paragraph 0028-0029, (2021/03/13)

Further, the formula I compound is a metal complex ligand of a homogeneous hydrogenation catalyst. The catalyst ligand is easy to synthesize, convenient to post-treat and easy for industrial production, and very high activity, productivity and enantioselectivity can be obtained by using thecatalyst. The compound is shown in the specification.

Preparation method of sacubitril intermediate

-

Paragraph 0033-0061, (2020/07/02)

The invention relates to a preparation method of a sacubitril intermediate, and belongs to the technical field of drug intermediate synthesis. The problems that existing operation is large in difficulty and not easy to control are solved. In the presence of a nickel salt catalyst and (R,R)-(-)-N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine, a compound (E)-(R)-5-biphenyl-4-yl-4-tert-butoxycarbonylamino-2-methylpent-2-enoic acid represented by formula II and ammonium formate are mixed in an alcohol solvent and undergo an asymmetric reduction reaction to obtain the corresponding sacubitril intermediate compound represented by formula I. The method does not need to be required to be in an inert atmosphere during production, and is more beneficial to operation. The cost of the raw materials is effectively reduced, and the effect of high yield can still be achieved.
