Check Digit Verification of cas no

The CAS Registry Mumber 790681-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,0,6,8 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 790681-33:
(8*7)+(7*9)+(6*0)+(5*6)+(4*8)+(3*1)+(2*3)+(1*3)=193
193 % 10 = 3
So 790681-33-3 is a valid CAS Registry Number.
