143870-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143870-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143870-52:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*0)+(2*5)+(1*2)=134
134 % 10 = 4
So 143870-52-4 is a valid CAS Registry Number.
