Check Digit Verification of cas no

The CAS Registry Mumber 1005774-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,7,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1005774-50:
(9*1)+(8*0)+(7*0)+(6*5)+(5*7)+(4*7)+(3*4)+(2*5)+(1*0)=124
124 % 10 = 4
So 1005774-50-4 is a valid CAS Registry Number.

Hindered Bronsted bases as Lewis base catalysts

Tabassum, Sobia,Sereda, Oksana,Reddy, Peddiahgari Vasu Govardhana,Wilhelm, Rene

, p. 4009 - 4016 (2009)

KHMDS and KOtBu are well established as strong, hindered, non-nucleophilic Bronsted bases. However, in the present work these bases are applied as highly active Lewis base catalysts for the formal [2+2] cycloaddition of ketenes with aldehydes and imines.
