1153687-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1153687-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,3,6,8 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1153687-20:
(9*1)+(8*1)+(7*5)+(6*3)+(5*6)+(4*8)+(3*7)+(2*2)+(1*0)=157
157 % 10 = 7
So 1153687-20-7 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
