Check Digit Verification of cas no

The CAS Registry Mumber 36267-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,2,6 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 36267-71:
(7*3)+(6*6)+(5*2)+(4*6)+(3*7)+(2*7)+(1*1)=127
127 % 10 = 7
So 36267-71-7 is a valid CAS Registry Number.
