Check Digit Verification of cas no

The CAS Registry Mumber 59270-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,7 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59270-23:
(7*5)+(6*9)+(5*2)+(4*7)+(3*0)+(2*2)+(1*3)=134
134 % 10 = 4
So 59270-23-4 is a valid CAS Registry Number.
