129012-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129012-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,1 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129012-20:
(8*1)+(7*2)+(6*9)+(5*0)+(4*1)+(3*2)+(2*2)+(1*0)=90
90 % 10 = 0
So 129012-20-0 is a valid CAS Registry Number.
