143057-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143057-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143057-83:
(8*1)+(7*4)+(6*3)+(5*0)+(4*5)+(3*7)+(2*8)+(1*3)=114
114 % 10 = 4
So 143057-83-4 is a valid CAS Registry Number.
