131406-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131406-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,0 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131406-56:
(8*1)+(7*3)+(6*1)+(5*4)+(4*0)+(3*6)+(2*5)+(1*6)=89
89 % 10 = 9
So 131406-56-9 is a valid CAS Registry Number.
