Check Digit Verification of cas no

The CAS Registry Mumber 839721-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,7,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 839721-90:
(8*8)+(7*3)+(6*9)+(5*7)+(4*2)+(3*1)+(2*9)+(1*0)=203
203 % 10 = 3
So 839721-90-3 is a valid CAS Registry Number.
