Check Digit Verification of cas no

The CAS Registry Mumber 73635-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,3 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73635-74:
(7*7)+(6*3)+(5*6)+(4*3)+(3*5)+(2*7)+(1*4)=142
142 % 10 = 2
So 73635-74-2 is a valid CAS Registry Number.
