Check Digit Verification of cas no

The CAS Registry Mumber 853021-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,0,2 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 853021-33:
(8*8)+(7*5)+(6*3)+(5*0)+(4*2)+(3*1)+(2*3)+(1*3)=137
137 % 10 = 7
So 853021-33-7 is a valid CAS Registry Number.
