803728-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 803728-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,3,7,2 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 803728-04:
(8*8)+(7*0)+(6*3)+(5*7)+(4*2)+(3*8)+(2*0)+(1*4)=153
153 % 10 = 3
So 803728-04-3 is a valid CAS Registry Number.

Hill, Bryan,Liu, Yong,Taylor, Scott D.
, p. 4285 - 4288 (2007/10/03)
(Chemical Equation Presented) α-Fluorosulfonamides were prepared by electrophilic fluorination of tertiary sulfonamides using N- fluorobenzenesulfonimide as fluorinating agent and utilizing the dimethoxybenzyl group (DMB) as a new sulfonamide protecting g
