120284-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120284-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,8 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120284-29:
(8*1)+(7*2)+(6*0)+(5*2)+(4*8)+(3*4)+(2*2)+(1*9)=89
89 % 10 = 9
So 120284-29-9 is a valid CAS Registry Number.
