Check Digit Verification of cas no

The CAS Registry Mumber 7778-50-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7778-50:
(6*7)+(5*7)+(4*7)+(3*8)+(2*5)+(1*0)=139
139 % 10 = 9
So 7778-50-9 is a valid CAS Registry Number.
