Check Digit Verification of cas no

The CAS Registry Mumber 9045-81-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9045-81:
(6*9)+(5*0)+(4*4)+(3*5)+(2*8)+(1*1)=102
102 % 10 = 2
So 9045-81-2 is a valid CAS Registry Number.
