Check Digit Verification of cas no

The CAS Registry Mumber 679003-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,9,0,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 679003-49:
(8*6)+(7*7)+(6*9)+(5*0)+(4*0)+(3*3)+(2*4)+(1*9)=177
177 % 10 = 7
So 679003-49-7 is a valid CAS Registry Number.
