Check Digit Verification of cas no

The CAS Registry Mumber 917247-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,4 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917247-90:
(8*9)+(7*1)+(6*7)+(5*2)+(4*4)+(3*7)+(2*9)+(1*0)=186
186 % 10 = 6
So 917247-90-6 is a valid CAS Registry Number.

Synthesis of α-hydroxy carboxylic acids via a nickel(II)- Catalyzed hydrogen transfer process

Tang, Guo,Cheng, Chien-Hong

supporting information; experimental part, p. 1918 - 1922 (2011/10/12)

A new catalytic system for β-alkylation of lactic acid with primary alcohols has been developed. In the presence of nickel(II) acetate tetrahydrate [Ni(OAc)2(H2O)4] and base, lactic acid reacts with primary alcohols to afford the corresponding coupled α-hydroxy carboxylic acids in good to excellent yields via a hydrogen transfer process without any hydrogen acceptor or hydrogen donor.
