Check Digit Verification of cas no

The CAS Registry Mumber 896718-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,6,7,1 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 896718-27:
(8*8)+(7*9)+(6*6)+(5*7)+(4*1)+(3*8)+(2*2)+(1*7)=237
237 % 10 = 7
So 896718-27-7 is a valid CAS Registry Number.

A convenient synthesis of medium-sized lactams through RCM reaction of oxyoxazolidinones

Kamimura, Akio,Tanaka, Keiichi,Hayashi, Takahiro,Omata, Yoji

, p. 3625 - 3627 (2007/10/03)

Oxyoxazolidinones, which are prepared from secondary O-acylmandelamides by treatment with TBSOTf, underwent the RCM reaction in the presence of Grubbs catalyst to give oxazoloazepines or oxazoloazecines, which were readily converted into N-unsubstituted seven-membered or eight-membered lactams by the reductive treatment.
