Check Digit Verification of cas no

The CAS Registry Mumber 136187-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,8 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136187-03:
(8*1)+(7*3)+(6*6)+(5*1)+(4*8)+(3*7)+(2*0)+(1*3)=126
126 % 10 = 6
So 136187-03-6 is a valid CAS Registry Number.
