Check Digit Verification of cas no
The CAS Registry Mumber 22675-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,7 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22675-81:
(7*2)+(6*2)+(5*6)+(4*7)+(3*5)+(2*8)+(1*1)=116
116 % 10 = 6
So 22675-81-6 is a valid CAS Registry Number.

Bigger is better: Sterically hindered dialkyl ureas undergo nucleophilic substitution at dramatically faster rates than their less hindered counterparts (see scheme). Steric decompression upon the formation of an intermediate isocyanate can explain this c
