100899-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100899-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,9 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100899-31:
(8*1)+(7*0)+(6*0)+(5*8)+(4*9)+(3*9)+(2*3)+(1*1)=118
118 % 10 = 8
So 100899-31-8 is a valid CAS Registry Number.

The Chemistry of N-Sulfonyl Enamines
Hegedus, Louis S.,Holden, Michael S.
, p. 1171 - 1174 (2007/10/02)
N-Tosyl enamines are available in multigram quantities using a palladium(II)-catalyzed cyclization process.This unusual class of compounds has limited nucleophilic character at the β-position, undergoing protonation and halogenation by N-halosuccinimides.
