Check Digit Verification of cas no

The CAS Registry Mumber 53267-67-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53267-67:
(7*5)+(6*3)+(5*2)+(4*6)+(3*7)+(2*6)+(1*7)=127
127 % 10 = 7
So 53267-67-7 is a valid CAS Registry Number.
