Check Digit Verification of cas no

The CAS Registry Mumber 75872-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,7 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75872-30:
(7*7)+(6*5)+(5*8)+(4*7)+(3*2)+(2*3)+(1*0)=159
159 % 10 = 9
So 75872-30-9 is a valid CAS Registry Number.
