Check Digit Verification of cas no

The CAS Registry Mumber 236427-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,4,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 236427-57:
(8*2)+(7*3)+(6*6)+(5*4)+(4*2)+(3*7)+(2*5)+(1*7)=139
139 % 10 = 9
So 236427-57-9 is a valid CAS Registry Number.
