Check Digit Verification of cas no

The CAS Registry Mumber 247074-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,7 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 247074-44:
(8*2)+(7*4)+(6*7)+(5*0)+(4*7)+(3*4)+(2*4)+(1*4)=138
138 % 10 = 8
So 247074-44-8 is a valid CAS Registry Number.
