1048703-14-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1048703-14-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,8,7,0 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1048703-14:
(9*1)+(8*0)+(7*4)+(6*8)+(5*7)+(4*0)+(3*3)+(2*1)+(1*4)=135
135 % 10 = 5
So 1048703-14-5 is a valid CAS Registry Number.

Preparation method of sitagliptin intermediate

-

, (2018/04/01)

The invention discloses a preparation method of a sitagliptin intermediate and belongs to the field of medicine synthesis. The invention provides a preparation method of a compound 2; the compound 2 is prepared without the need of a catalyst and a resolving agent which have a high price and harsh low-temperature conditions, so that the cost is reduced to the great extent; the preparation method has the advantages of simple technology, high purity and high yield and is suitable for mass production.

INTERMEDIATES OF SITAGLIPTIN AND PREPARATION PROCESS THEREOF

-

, (2013/11/05)

Disclosed are intermediates of Sitagliptin, a preparation process thereof, and a process for synthesizing Sitagliptin using these intermediates. Sitagliptin is synthesized by using chiral amino compounds as a raw material, without having to build a chiral center with a chiral asymmetric catalytic hydrogenation, and high-pressure hydrogenation is avoided.
