89647-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89647-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,4 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89647-13:
(7*8)+(6*9)+(5*6)+(4*4)+(3*7)+(2*1)+(1*3)=182
182 % 10 = 2
So 89647-13-2 is a valid CAS Registry Number.

Kuroki, Yoshiaki,Lett, Robert
, p. 197 - 200 (2007/10/02)
Phenyl vinyl sulfone and p-tolyl isobutenyl sulfone are convenient reagents for protecting SH groups via the Michael adduct.Protection and deprotection can be achieved in high yields under mild basic conditions, in protic or aprotic solvents.
