Check Digit Verification of cas no

The CAS Registry Mumber 51643-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,4 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51643-95:
(7*5)+(6*1)+(5*6)+(4*4)+(3*3)+(2*9)+(1*5)=119
119 % 10 = 9
So 51643-95-9 is a valid CAS Registry Number.
