Check Digit Verification of cas no

The CAS Registry Mumber 470670-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,0,6,7 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 470670-74:
(8*4)+(7*7)+(6*0)+(5*6)+(4*7)+(3*0)+(2*7)+(1*4)=157
157 % 10 = 7
So 470670-74-7 is a valid CAS Registry Number.

Development of a rapid, room-temperature dynamic kinetic resolution for efficient asymmetric synthesis of α-aryl amino acids

Hang, Jianfeng,Li, Hongming,Deng, Li

, p. 3321 - 3324 (2007/10/03)

equation presented A rapid, highly efficient and general dynamic kinetic resolution (DKR) of racemic α-aryl UNCAs with the dual-function catalysis of modified cinchona alkaloid was accomplished at room temperature. This DKR led to the development of a highly enantioselective catalytic method for the practical synthesis of a wide range of α-aryl and α-heteroaryl amino acids in 89-92% ee and 86-95% yield from racemic UNCAs.
