Check Digit Verification of cas no

The CAS Registry Mumber 13730-46-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,3 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13730-46:
(7*1)+(6*3)+(5*7)+(4*3)+(3*0)+(2*4)+(1*6)=86
86 % 10 = 6
So 13730-46-6 is a valid CAS Registry Number.
