Check Digit Verification of cas no

The CAS Registry Mumber 778638-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,6,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 778638-72:
(8*7)+(7*7)+(6*8)+(5*6)+(4*3)+(3*8)+(2*7)+(1*2)=235
235 % 10 = 5
So 778638-72-5 is a valid CAS Registry Number.
