1403576-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1403576-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,5,7 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1403576-53:
(9*1)+(8*4)+(7*0)+(6*3)+(5*5)+(4*7)+(3*6)+(2*5)+(1*3)=143
143 % 10 = 3
So 1403576-53-3 is a valid CAS Registry Number.
