Check Digit Verification of cas no

The CAS Registry Mumber 5909-37-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,0 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5909-37:
(6*5)+(5*9)+(4*0)+(3*9)+(2*3)+(1*7)=115
115 % 10 = 5
So 5909-37-5 is a valid CAS Registry Number.
