120353-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120353-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,5 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120353-55:
(8*1)+(7*2)+(6*0)+(5*3)+(4*5)+(3*3)+(2*5)+(1*5)=81
81 % 10 = 1
So 120353-55-1 is a valid CAS Registry Number.
