970-18-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 970-18-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 970-18:
(5*9)+(4*7)+(3*0)+(2*1)+(1*8)=83
83 % 10 = 3
So 970-18-3 is a valid CAS Registry Number.
