Check Digit Verification of cas no

The CAS Registry Mumber 6031-49-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,3 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6031-49:
(6*6)+(5*0)+(4*3)+(3*1)+(2*4)+(1*9)=68
68 % 10 = 8
So 6031-49-8 is a valid CAS Registry Number.
