91374-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91374-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,7 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91374-71:
(7*9)+(6*1)+(5*3)+(4*7)+(3*4)+(2*7)+(1*1)=139
139 % 10 = 9
So 91374-71-9 is a valid CAS Registry Number.
