1426341-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1426341-72-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,3,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1426341-72:
(9*1)+(8*4)+(7*2)+(6*6)+(5*3)+(4*4)+(3*1)+(2*7)+(1*2)=141
141 % 10 = 1
So 1426341-72-1 is a valid CAS Registry Number.
