Check Digit Verification of cas no

The CAS Registry Mumber 87241-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87241-97:
(7*8)+(6*7)+(5*2)+(4*4)+(3*1)+(2*9)+(1*7)=152
152 % 10 = 2
So 87241-97-2 is a valid CAS Registry Number.
