122053-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122053-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,5 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122053-98:
(8*1)+(7*2)+(6*2)+(5*0)+(4*5)+(3*3)+(2*9)+(1*8)=89
89 % 10 = 9
So 122053-98-9 is a valid CAS Registry Number.
