83620-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83620-64-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83620-64:
(7*8)+(6*3)+(5*6)+(4*2)+(3*0)+(2*6)+(1*4)=128
128 % 10 = 8
So 83620-64-8 is a valid CAS Registry Number.
