Check Digit Verification of cas no

The CAS Registry Mumber 3987-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3987-48:
(6*3)+(5*9)+(4*8)+(3*7)+(2*4)+(1*8)=132
132 % 10 = 2
So 3987-48-2 is a valid CAS Registry Number.
