496972-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 496972-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,6,9,7 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 496972-55:
(8*4)+(7*9)+(6*6)+(5*9)+(4*7)+(3*2)+(2*5)+(1*5)=225
225 % 10 = 5
So 496972-55-5 is a valid CAS Registry Number.
