Check Digit Verification of cas no

The CAS Registry Mumber 2509-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,0 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2509-34:
(6*2)+(5*5)+(4*0)+(3*9)+(2*3)+(1*4)=74
74 % 10 = 4
So 2509-34-4 is a valid CAS Registry Number.
