905589-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905589-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,5,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 905589-33:
(8*9)+(7*0)+(6*5)+(5*5)+(4*8)+(3*9)+(2*3)+(1*3)=195
195 % 10 = 5
So 905589-33-5 is a valid CAS Registry Number.
