143427-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143427-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,2 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143427-09:
(8*1)+(7*4)+(6*3)+(5*4)+(4*2)+(3*7)+(2*0)+(1*9)=112
112 % 10 = 2
So 143427-09-2 is a valid CAS Registry Number.
