Check Digit Verification of cas no

The CAS Registry Mumber 1137669-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,7,6,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1137669-53:
(9*1)+(8*1)+(7*3)+(6*7)+(5*6)+(4*6)+(3*9)+(2*5)+(1*3)=174
174 % 10 = 4
So 1137669-53-4 is a valid CAS Registry Number.
