129801-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129801-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129801-56:
(8*1)+(7*2)+(6*9)+(5*8)+(4*0)+(3*1)+(2*5)+(1*6)=135
135 % 10 = 5
So 129801-56-5 is a valid CAS Registry Number.
