Check Digit Verification of cas no

The CAS Registry Mumber 65891-80-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65891-80:
(7*6)+(6*5)+(5*8)+(4*9)+(3*1)+(2*8)+(1*0)=167
167 % 10 = 7
So 65891-80-7 is a valid CAS Registry Number.

Novel method for synthesizing D5-diazepam

-

, (2021/06/09)

The invention discloses a novel method for synthesizing D5-diazepam, belongs to the field of organic chemistry, and can be applied to the field of forensic poison analysis. According to the method disclosed by the invention, 2-amino-5-chlorobenzyl cyanide and D5-phenylboronic acid are used as raw materials, and the D5-diazepam is obtained by carrying out addition, cyclization and methylation processes on cyano groups by palladium-catalyzed arylboronic acid and carrying out separation and purification. The method has the advantages of mild reaction conditions, short synthesis steps, high yield and the like, and the synthesized D5-diazepam has high purity and good stability and can be used as an internal standard substance for forensic poison analysis quality control to realize domestic substitution.
