80366-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80366-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,6 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80366-21:
(7*8)+(6*0)+(5*3)+(4*6)+(3*6)+(2*2)+(1*1)=118
118 % 10 = 8
So 80366-21-8 is a valid CAS Registry Number.
