1443276-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1443276-27-4 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, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1443276-27:
(9*1)+(8*4)+(7*4)+(6*3)+(5*2)+(4*7)+(3*6)+(2*2)+(1*7)=154
154 % 10 = 4
So 1443276-27-4 is a valid CAS Registry Number.
