Check Digit Verification of cas no

The CAS Registry Mumber 1347654-84-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,7,6,5 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1347654-84:
(9*1)+(8*3)+(7*4)+(6*7)+(5*6)+(4*5)+(3*4)+(2*8)+(1*4)=185
185 % 10 = 5
So 1347654-84-5 is a valid CAS Registry Number.
