313471-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 313471-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,4,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 313471-97:
(8*3)+(7*1)+(6*3)+(5*4)+(4*7)+(3*1)+(2*9)+(1*7)=125
125 % 10 = 5
So 313471-97-5 is a valid CAS Registry Number.
