142998-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142998-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,9 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142998-06:
(8*1)+(7*4)+(6*2)+(5*9)+(4*9)+(3*8)+(2*0)+(1*6)=159
159 % 10 = 9
So 142998-06-9 is a valid CAS Registry Number.
