Check Digit Verification of cas no

The CAS Registry Mumber 138307-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138307-77:
(8*1)+(7*3)+(6*8)+(5*3)+(4*0)+(3*7)+(2*7)+(1*7)=134
134 % 10 = 4
So 138307-77-4 is a valid CAS Registry Number.
