91424-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91424-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,2 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91424-45:
(7*9)+(6*1)+(5*4)+(4*2)+(3*4)+(2*4)+(1*5)=122
122 % 10 = 2
So 91424-45-2 is a valid CAS Registry Number.
