83821-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83821-24-3 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, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83821-24:
(7*8)+(6*3)+(5*8)+(4*2)+(3*1)+(2*2)+(1*4)=133
133 % 10 = 3
So 83821-24-3 is a valid CAS Registry Number.
