Check Digit Verification of cas no

The CAS Registry Mumber 1950-75-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1950-75:
(6*1)+(5*9)+(4*5)+(3*0)+(2*7)+(1*5)=90
90 % 10 = 0
So 1950-75-0 is a valid CAS Registry Number.
