Check Digit Verification of cas no

The CAS Registry Mumber 70197-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,9 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70197-04:
(7*7)+(6*0)+(5*1)+(4*9)+(3*7)+(2*0)+(1*4)=115
115 % 10 = 5
So 70197-04-5 is a valid CAS Registry Number.
