Check Digit Verification of cas no

The CAS Registry Mumber 134868-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,6 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134868-79:
(8*1)+(7*3)+(6*4)+(5*8)+(4*6)+(3*8)+(2*7)+(1*9)=164
164 % 10 = 4
So 134868-79-4 is a valid CAS Registry Number.
