91534-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91534-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,3 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91534-14:
(7*9)+(6*1)+(5*5)+(4*3)+(3*4)+(2*1)+(1*4)=124
124 % 10 = 4
So 91534-14-4 is a valid CAS Registry Number.
