1443276-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1443276-18-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,2,7 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1443276-18:
(9*1)+(8*4)+(7*4)+(6*3)+(5*2)+(4*7)+(3*6)+(2*1)+(1*8)=153
153 % 10 = 3
So 1443276-18-3 is a valid CAS Registry Number.
