Check Digit Verification of cas no

The CAS Registry Mumber 90693-46-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,9 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90693-46:
(7*9)+(6*0)+(5*6)+(4*9)+(3*3)+(2*4)+(1*6)=152
152 % 10 = 2
So 90693-46-2 is a valid CAS Registry Number.
