59456-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59456-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,5 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59456-69:
(7*5)+(6*9)+(5*4)+(4*5)+(3*6)+(2*6)+(1*9)=168
168 % 10 = 8
So 59456-69-8 is a valid CAS Registry Number.
