143232-48-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143232-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,3 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143232-48:
(8*1)+(7*4)+(6*3)+(5*2)+(4*3)+(3*2)+(2*4)+(1*8)=98
98 % 10 = 8
So 143232-48-8 is a valid CAS Registry Number.
