Check Digit Verification of cas no

The CAS Registry Mumber 81238-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,3 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81238-27:
(7*8)+(6*1)+(5*2)+(4*3)+(3*8)+(2*2)+(1*7)=119
119 % 10 = 9
So 81238-27-9 is a valid CAS Registry Number.
