Check Digit Verification of cas no

The CAS Registry Mumber 83994-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,9 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83994-50:
(7*8)+(6*3)+(5*9)+(4*9)+(3*4)+(2*5)+(1*0)=177
177 % 10 = 7
So 83994-50-7 is a valid CAS Registry Number.
