131581-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131581-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,8 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131581-73:
(8*1)+(7*3)+(6*1)+(5*5)+(4*8)+(3*1)+(2*7)+(1*3)=112
112 % 10 = 2
So 131581-73-2 is a valid CAS Registry Number.
