40934-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40934-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,3 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40934-72:
(7*4)+(6*0)+(5*9)+(4*3)+(3*4)+(2*7)+(1*2)=113
113 % 10 = 3
So 40934-72-3 is a valid CAS Registry Number.

3-Trimethylsilylcycloalkylidenes. γ-Silyl vs γ-Hydrogen Migration to Carbene Centers
Creary, Xavier
, p. 11378 - 11387 (2015/12/01)
A series of γ-trimethylsilyl-substituted carbenes have been studied experimentally and by computational methods. In an acyclic system, 1,3-trimethylsilyl migration successfully competes with 1,3-hydrogen migration to the carbene center. The behavior of cy
