Check Digit Verification of cas no

The CAS Registry Mumber 54750-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,5 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54750-23:
(7*5)+(6*4)+(5*7)+(4*5)+(3*0)+(2*2)+(1*3)=121
121 % 10 = 1
So 54750-23-1 is a valid CAS Registry Number.
