Check Digit Verification of cas no

The CAS Registry Mumber 875439-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,4,3 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 875439-71:
(8*8)+(7*7)+(6*5)+(5*4)+(4*3)+(3*9)+(2*7)+(1*1)=217
217 % 10 = 7
So 875439-71-7 is a valid CAS Registry Number.
