29840-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29840-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,8,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 29840-05:
(7*2)+(6*9)+(5*8)+(4*4)+(3*0)+(2*0)+(1*5)=129
129 % 10 = 9
So 29840-05-9 is a valid CAS Registry Number.
