Check Digit Verification of cas no

The CAS Registry Mumber 189764-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,6 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189764-38:
(8*1)+(7*8)+(6*9)+(5*7)+(4*6)+(3*4)+(2*3)+(1*8)=203
203 % 10 = 3
So 189764-38-3 is a valid CAS Registry Number.
