Check Digit Verification of cas no

The CAS Registry Mumber 1396317-78-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,6,3,1 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1396317-78:
(9*1)+(8*3)+(7*9)+(6*6)+(5*3)+(4*1)+(3*7)+(2*7)+(1*8)=194
194 % 10 = 4
So 1396317-78-4 is a valid CAS Registry Number.
