1338443-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338443-31-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,4,4 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338443-31:
(9*1)+(8*3)+(7*3)+(6*8)+(5*4)+(4*4)+(3*3)+(2*3)+(1*1)=154
154 % 10 = 4
So 1338443-31-4 is a valid CAS Registry Number.
