143642-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143642-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,4 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143642-99:
(8*1)+(7*4)+(6*3)+(5*6)+(4*4)+(3*2)+(2*9)+(1*9)=133
133 % 10 = 3
So 143642-99-3 is a valid CAS Registry Number.
