240426-49-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 240426-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,4,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 240426-49:
(8*2)+(7*4)+(6*0)+(5*4)+(4*2)+(3*6)+(2*4)+(1*9)=107
107 % 10 = 7
So 240426-49-7 is a valid CAS Registry Number.
