1281343-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1281343-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,3,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1281343-72:
(9*1)+(8*2)+(7*8)+(6*1)+(5*3)+(4*4)+(3*3)+(2*7)+(1*2)=143
143 % 10 = 3
So 1281343-72-3 is a valid CAS Registry Number.
