1331843-56-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1331843-56-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,8,4 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1331843-56:
(9*1)+(8*3)+(7*3)+(6*1)+(5*8)+(4*4)+(3*3)+(2*5)+(1*6)=141
141 % 10 = 1
So 1331843-56-1 is a valid CAS Registry Number.
