143115-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143115-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,1 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143115-99:
(8*1)+(7*4)+(6*3)+(5*1)+(4*1)+(3*5)+(2*9)+(1*9)=105
105 % 10 = 5
So 143115-99-5 is a valid CAS Registry Number.
