Check Digit Verification of cas no

The CAS Registry Mumber 1256249-22-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256249-22:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*4)+(3*9)+(2*2)+(1*2)=155
155 % 10 = 5
So 1256249-22-5 is a valid CAS Registry Number.

Addition of acetone towards β-cyano-α-oxoesters catalyzed by L-proline: Dynamic kinetic resolution

Wang, Yajun,Zhang, Yawen

experimental part, p. 1267 - 1271 (2010/11/17)

β-Cyano-α-oxoesters were found to undergo asymmetric aldol addition reaction with acetone in the presence of 10mol% of L-proline. With the racemic starting material, dynamic kinetic resolution (DKR) was achieved in quantitative yields with good diastreros
