320590-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 320590-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,5,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 320590-45:
(8*3)+(7*2)+(6*0)+(5*5)+(4*9)+(3*0)+(2*4)+(1*5)=112
112 % 10 = 2
So 320590-45-2 is a valid CAS Registry Number.
