Check Digit Verification of cas no

The CAS Registry Mumber 740799-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,7,9 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 740799-11:
(8*7)+(7*4)+(6*0)+(5*7)+(4*9)+(3*9)+(2*1)+(1*1)=185
185 % 10 = 5
So 740799-11-5 is a valid CAS Registry Number.
