93471-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93471-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,4,7 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93471-93:
(7*9)+(6*3)+(5*4)+(4*7)+(3*1)+(2*9)+(1*3)=153
153 % 10 = 3
So 93471-93-3 is a valid CAS Registry Number.

, p. 3583 - 3586 (2007/10/02)
Diels-Alder reaction of dienyl α-methacrylthioimidates has been investigated under thermal or Lewis acid or protonic acid catalyzed conditions.The utility of the reaction is shown by desulfurative ring contraction of bicyclo to bicyclosystem.
