Check Digit Verification of cas no

The CAS Registry Mumber 765949-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,5,9,4 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 765949-23:
(8*7)+(7*6)+(6*5)+(5*9)+(4*4)+(3*9)+(2*2)+(1*3)=223
223 % 10 = 3
So 765949-23-3 is a valid CAS Registry Number.
