Check Digit Verification of cas no

The CAS Registry Mumber 1025830-09-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,8,3 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1025830-09:
(9*1)+(8*0)+(7*2)+(6*5)+(5*8)+(4*3)+(3*0)+(2*0)+(1*9)=114
114 % 10 = 4
So 1025830-09-4 is a valid CAS Registry Number.

PROCESS FOR PRODUCTION OF MONO-SUBSTITUTED ALKYLATED COMPOUND USING ALDIMINE OR DERIVATIVE THEREOF

-

Page/Page column 101-102, (2008/06/13)

Disclosed is a process for producing an asymmetric mono-substituted alkylated compound of an α-amino acid which is represented by a specific formula by using an aldimine-type Schiff base. In the process, the alkylation of an aldimine-type Schiff base in a medium in the presence of an optically active quaternary ammonium salt phase transfer catalyst and an inorganic base is started, and subsequently the reaction is quenched at any time preceding the completion of the stoichimetrical reaction, thereby yielding a mono-substituted alkylated product having a high optical purity.
