131456-75-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131456-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,5 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131456-75:
(8*1)+(7*3)+(6*1)+(5*4)+(4*5)+(3*6)+(2*7)+(1*5)=112
112 % 10 = 2
So 131456-75-2 is a valid CAS Registry Number.
