80021-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80021-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80021-12:
(7*8)+(6*0)+(5*0)+(4*2)+(3*1)+(2*1)+(1*2)=71
71 % 10 = 1
So 80021-12-1 is a valid CAS Registry Number.
