131334-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131334-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,3 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131334-92:
(8*1)+(7*3)+(6*1)+(5*3)+(4*3)+(3*4)+(2*9)+(1*2)=94
94 % 10 = 4
So 131334-92-4 is a valid CAS Registry Number.
