905565-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905565-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,5,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 905565-99:
(8*9)+(7*0)+(6*5)+(5*5)+(4*6)+(3*5)+(2*9)+(1*9)=193
193 % 10 = 3
So 905565-99-3 is a valid CAS Registry Number.
