129880-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129880-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,8 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129880-98:
(8*1)+(7*2)+(6*9)+(5*8)+(4*8)+(3*0)+(2*9)+(1*8)=174
174 % 10 = 4
So 129880-98-4 is a valid CAS Registry Number.
