131291-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131291-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131291-40:
(8*1)+(7*3)+(6*1)+(5*2)+(4*9)+(3*1)+(2*4)+(1*0)=92
92 % 10 = 2
So 131291-40-2 is a valid CAS Registry Number.
