Check Digit Verification of cas no

The CAS Registry Mumber 141739-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,3 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141739-95:
(8*1)+(7*4)+(6*1)+(5*7)+(4*3)+(3*9)+(2*9)+(1*5)=139
139 % 10 = 9
So 141739-95-9 is a valid CAS Registry Number.
