Check Digit Verification of cas no

The CAS Registry Mumber 137726-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,2 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137726-69:
(8*1)+(7*3)+(6*7)+(5*7)+(4*2)+(3*6)+(2*6)+(1*9)=153
153 % 10 = 3
So 137726-69-3 is a valid CAS Registry Number.
