Check Digit Verification of cas no

The CAS Registry Mumber 1312997-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,9 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1312997-39:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*9)+(3*7)+(2*3)+(1*9)=169
169 % 10 = 9
So 1312997-39-9 is a valid CAS Registry Number.

Nonenzymatic dynamic kinetic resolution of α-(arylthio)- and α-(alkylthio)alkanoic acids

Yang, Xing,Birman, Vladimir B.

, p. 5553 - 5555 (2011/07/09)

Dynamic solution: The title acids undergo dynamic kinetic resolution during an enantioselective esterification catalyzed by (S)-homobenzotetramisole ((S)-HBTM; see scheme). This method extends the scope of the carboxylic acid derivatives that are amenable to the nonenzymatic version of this transformation. Copyright
