143674-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143674-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,7 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143674-55:
(8*1)+(7*4)+(6*3)+(5*6)+(4*7)+(3*4)+(2*5)+(1*5)=139
139 % 10 = 9
So 143674-55-9 is a valid CAS Registry Number.
