129508-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129508-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,0 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129508-04:
(8*1)+(7*2)+(6*9)+(5*5)+(4*0)+(3*8)+(2*0)+(1*4)=129
129 % 10 = 9
So 129508-04-9 is a valid CAS Registry Number.
