Check Digit Verification of cas no

The CAS Registry Mumber 303012-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,0,1 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 303012-46:
(8*3)+(7*0)+(6*3)+(5*0)+(4*1)+(3*2)+(2*4)+(1*6)=66
66 % 10 = 6
So 303012-46-6 is a valid CAS Registry Number.
