110426-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110426-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,4,2 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 110426-74:
(8*1)+(7*1)+(6*0)+(5*4)+(4*2)+(3*6)+(2*7)+(1*4)=79
79 % 10 = 9
So 110426-74-9 is a valid CAS Registry Number.
