Check Digit Verification of cas no

The CAS Registry Mumber 1267437-95-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,4,3 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1267437-95:
(9*1)+(8*2)+(7*6)+(6*7)+(5*4)+(4*3)+(3*7)+(2*9)+(1*5)=185
185 % 10 = 5
So 1267437-95-5 is a valid CAS Registry Number.
