Check Digit Verification of cas no
The CAS Registry Mumber 205445-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,4,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 205445-52:
(8*2)+(7*0)+(6*5)+(5*4)+(4*4)+(3*5)+(2*5)+(1*2)=109
109 % 10 = 9
So 205445-52-9 is a valid CAS Registry Number.
