668980-22-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 668980-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,8,9,8 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 668980-22:
(8*6)+(7*6)+(6*8)+(5*9)+(4*8)+(3*0)+(2*2)+(1*2)=221
221 % 10 = 1
So 668980-22-1 is a valid CAS Registry Number.
