455333-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 455333-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,5,3,3 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 455333-20:
(8*4)+(7*5)+(6*5)+(5*3)+(4*3)+(3*3)+(2*2)+(1*0)=137
137 % 10 = 7
So 455333-20-7 is a valid CAS Registry Number.
