Check Digit Verification of cas no

The CAS Registry Mumber 91004-93-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,0 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91004-93:
(7*9)+(6*1)+(5*0)+(4*0)+(3*4)+(2*9)+(1*3)=102
102 % 10 = 2
So 91004-93-2 is a valid CAS Registry Number.
