Check Digit Verification of cas no

The CAS Registry Mumber 137433-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137433-75:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*3)+(2*7)+(1*5)=131
131 % 10 = 1
So 137433-75-1 is a valid CAS Registry Number.
