213263-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213263-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,6 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213263-05:
(8*2)+(7*1)+(6*3)+(5*2)+(4*6)+(3*3)+(2*0)+(1*5)=89
89 % 10 = 9
So 213263-05-9 is a valid CAS Registry Number.
