83821-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83821-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,2 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83821-31:
(7*8)+(6*3)+(5*8)+(4*2)+(3*1)+(2*3)+(1*1)=132
132 % 10 = 2
So 83821-31-2 is a valid CAS Registry Number.
