Check Digit Verification of cas no

The CAS Registry Mumber 70333-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,3 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70333-96:
(7*7)+(6*0)+(5*3)+(4*3)+(3*3)+(2*9)+(1*6)=109
109 % 10 = 9
So 70333-96-9 is a valid CAS Registry Number.
