Check Digit Verification of cas no

The CAS Registry Mumber 87239-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,3 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87239-92:
(7*8)+(6*7)+(5*2)+(4*3)+(3*9)+(2*9)+(1*2)=167
167 % 10 = 7
So 87239-92-7 is a valid CAS Registry Number.
