Check Digit Verification of cas no

The CAS Registry Mumber 1172633-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,6,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1172633-40:
(9*1)+(8*1)+(7*7)+(6*2)+(5*6)+(4*3)+(3*3)+(2*4)+(1*0)=137
137 % 10 = 7
So 1172633-40-7 is a valid CAS Registry Number.

Novel stereocontrolled synthesis of highly functionalized cyclobutanes by epoxide opening through a carbanion intermediate in heteroconjugate addition

Adachi, Masaatsu,Yamauchi, Eiji,Komada, Takema,Isobe, Minoru

scheme or table, p. 1157 - 1161 (2009/10/17)

We have demonstrated a new cyclobutane ring formation from the trans-1,2-disubstituted epoxides through intramolecular carbanion opening process. In this reaction, the nucleophilic carbanion is generated not via α-proton abstraction but via heteroconjugat
