Check Digit Verification of cas no

The CAS Registry Mumber 930272-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,0,2,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 930272-50:
(8*9)+(7*3)+(6*0)+(5*2)+(4*7)+(3*2)+(2*5)+(1*0)=147
147 % 10 = 7
So 930272-50-7 is a valid CAS Registry Number.
