29800-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29800-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,8,0 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29800-80:
(7*2)+(6*9)+(5*8)+(4*0)+(3*0)+(2*8)+(1*0)=124
124 % 10 = 4
So 29800-80-4 is a valid CAS Registry Number.
