668980-23-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 668980-23-2 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 668980-23:
(8*6)+(7*6)+(6*8)+(5*9)+(4*8)+(3*0)+(2*2)+(1*3)=222
222 % 10 = 2
So 668980-23-2 is a valid CAS Registry Number.
