1628741-32-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1628741-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,8,7,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1628741-32:
(9*1)+(8*6)+(7*2)+(6*8)+(5*7)+(4*4)+(3*1)+(2*3)+(1*2)=181
181 % 10 = 1
So 1628741-32-1 is a valid CAS Registry Number.

Two radical-mediated processes of activated alkenes, namely arylphosphonylation and arylazidation, are described. The difunctionalization of alkenes by a tandem process that involves radical addition, 1,4-aryl migration, and desulfonylation generates α-ar
