Check Digit Verification of cas no

The CAS Registry Mumber 74357-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,5 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74357-30:
(7*7)+(6*4)+(5*3)+(4*5)+(3*7)+(2*3)+(1*0)=135
135 % 10 = 5
So 74357-30-5 is a valid CAS Registry Number.
