Check Digit Verification of cas no

The CAS Registry Mumber 133405-30-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133405-30:
(8*1)+(7*3)+(6*3)+(5*4)+(4*0)+(3*5)+(2*3)+(1*0)=88
88 % 10 = 8
So 133405-30-8 is a valid CAS Registry Number.
