Check Digit Verification of cas no

The CAS Registry Mumber 1399841-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,8,4 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1399841-03:
(9*1)+(8*3)+(7*9)+(6*9)+(5*8)+(4*4)+(3*1)+(2*0)+(1*3)=212
212 % 10 = 2
So 1399841-03-2 is a valid CAS Registry Number.

Catalytic dynamic kinetic resolutions with N-heterocyclic carbenes: Asymmetric synthesis of highly substituted β-lactones

Cohen, Daniel T.,Eichman, Chad C.,Phillips, Eric M.,Zarefsky, Emily R.,Scheidt, Karl A.

, p. 7309 - 7313 (2012/08/28)

New DKR type: An N-heterocyclic carbene (NHC)-catalyzed dynamic kinetic resolution of racemic α-substituted β-keto esters has been developed. This method relies on the epimerization of an NHC-enol intermediate before subsequent aldol/acylation events. Hig
