Check Digit Verification of cas no

The CAS Registry Mumber 193765-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,7,6 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 193765-68:
(8*1)+(7*9)+(6*3)+(5*7)+(4*6)+(3*5)+(2*6)+(1*8)=183
183 % 10 = 3
So 193765-68-3 is a valid CAS Registry Number.
