Check Digit Verification of cas no
The CAS Registry Mumber 212757-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,7,5 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 212757-09:
(8*2)+(7*1)+(6*2)+(5*7)+(4*5)+(3*7)+(2*0)+(1*9)=120
120 % 10 = 0
So 212757-09-0 is a valid CAS Registry Number.

A Practical Telescoped Three-Step Sequence for the Preparation of (1 R,2 R)-2-(4-Bromobenzoyl)cyclohexanecarboxylic Acid: A Key Building Block Used in One of Our Drug Development Projects
Karlsson, Staffan,Bergman, Rolf,Broddefalk, Johan,L?fberg, Christian,Moore, Peter R.,Stark, Andrew,Emten?s, Hans
, p. 618 - 624 (2018)
A large-scale, robust telescoped process involving acid chloride generation and Friedel-Crafts acylation followed by hydrolysis of an ester was developed for the manufacture of a homochiral disubstituted cyclohexane. Chromatography was avoided, and instea
