91873-51-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91873-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91873-51:
(7*9)+(6*1)+(5*8)+(4*7)+(3*3)+(2*5)+(1*1)=157
157 % 10 = 7
So 91873-51-7 is a valid CAS Registry Number.

REACTIONS OF ENOL SILYL ETHERS WITH N-HALOSUCCINIMIDE - A STEPWISE PROCESS.
Hambly, G. F.,Chan, T. H.
, p. 2563 - 2566 (2007/10/02)
The N-chlorosuccinimide (NSC) reaction of a number of cyclic and acyclic trimethylsilyl enol ethers was investigated.Based on product analyses, the mechanism of the reaction is postulated to involve a step-wise process.
