4774-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4774-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4774-91:
(6*4)+(5*7)+(4*7)+(3*4)+(2*9)+(1*1)=118
118 % 10 = 8

Preparative electrochemical oxidation of cyclic peralkylsilanes
Becker,Shakkour,West
, p. 5633 - 5636 (2007/10/02)
The electrochemical oxidation of cyclic peralkylsilanes undergo ring opening followed by further Si-Si bond cleavage and reaction with BF4- to form α,ω-difluorosilanes, F-(SiR2)(n)-F, as major products.
