91502-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91502-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,0 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91502-44:
(7*9)+(6*1)+(5*5)+(4*0)+(3*2)+(2*4)+(1*4)=112
112 % 10 = 2
So 91502-44-2 is a valid CAS Registry Number.
