Check Digit Verification of cas no

The CAS Registry Mumber 7535-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,3 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7535-21:
(6*7)+(5*5)+(4*3)+(3*5)+(2*2)+(1*1)=99
99 % 10 = 9
So 7535-21-9 is a valid CAS Registry Number.
