Check Digit Verification of cas no

The CAS Registry Mumber 109810-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,1 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109810-35:
(8*1)+(7*0)+(6*9)+(5*8)+(4*1)+(3*0)+(2*3)+(1*5)=117
117 % 10 = 7
So 109810-35-7 is a valid CAS Registry Number.

Green synthesis method of polyaryl substituted methanol

-

Paragraph 0127-0131; 0257-0261, (2021/04/17)

The invention relates to a green synthesis method of polyaryl substituted methanol, in particular to a method for efficiently synthesizing polyaryl substituted methanol in a polar aprotic solvent under the condition of an oxidizing agent by taking polyaryl substituted methane as a raw material and alkali as an additive. The method provided by the invention is green and environment-friendly, avoids using expensive metal catalysts, and has the advantages of low cost, few reaction steps, short time, high yield and the like.

Iron-catalyzed C-H bond functionalization for the exclusive synthesis of pyrido[1,2-a]indoles or triarylmethanols

Karthikeyan, Iyyanar,Sekar, Govindasamy

, p. 8055 - 8063 (2015/01/09)

The efficient and selective iron-catalyzed C-H activation of 2-benzhydrylpyridine derivatives was employed for the preparation of pyrido[1,2-a]indoles through an intramolecular C-H amination reaction. In the presence of molecular oxygen as the sole oxidant, the same 2-benzhydrylpyridines were also used for the synthesis of the corresponding tertiary alcohols. In these approaches, the iron catalyst was used to selectively activate the C(sp2)-H bond of 2-benzhydrylpyridine, in the case of the intramolecular ring-closing C-H amination reaction in which the pyridine nitrogen atom was a directing group as well as a nucleophile, and the C(sp3)-H bond of the same compound, in the case of the oxidation reaction to give the corresponding triaryl carbinol.
