142835-62-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142835-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,3 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142835-62:
(8*1)+(7*4)+(6*2)+(5*8)+(4*3)+(3*5)+(2*6)+(1*2)=129
129 % 10 = 9
So 142835-62-9 is a valid CAS Registry Number.
