1443640-75-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1443640-75-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,6,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1443640-75:
(9*1)+(8*4)+(7*4)+(6*3)+(5*6)+(4*4)+(3*0)+(2*7)+(1*5)=152
152 % 10 = 2
So 1443640-75-2 is a valid CAS Registry Number.
