943249-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 943249-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,2,4 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 943249-24:
(8*9)+(7*4)+(6*3)+(5*2)+(4*4)+(3*9)+(2*2)+(1*4)=179
179 % 10 = 9
So 943249-24-9 is a valid CAS Registry Number.
