129-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129-83-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129-83:
(5*1)+(4*2)+(3*9)+(2*8)+(1*3)=59
59 % 10 = 9
So 129-83-9 is a valid CAS Registry Number.
