Check Digit Verification of cas no

The CAS Registry Mumber 1055423-27-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,5,4,2 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1055423-27:
(9*1)+(8*0)+(7*5)+(6*5)+(5*4)+(4*2)+(3*3)+(2*2)+(1*7)=122
122 % 10 = 2
So 1055423-27-2 is a valid CAS Registry Number.

Stereochemical diversity in asymmetric cyclization via memory of chirality

Kawabata, Takeo,Matsuda, Seiji,Kawakami, Shimpei,Monguchi, Daiki,Moriyama, Katsuhiko

, p. 15394 - 15395 (2007/10/03)

An enantiodivergent asymmetric cyclization of N-Boc-N-ω-bromoalkyl-α-amino acid derivatives has been developed. With potassium amide bases in DMF, cyclization proceeds with retention of configuration, while inversion of configuration was observed with lit
