77455-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77455-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,5 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77455-23:
(7*7)+(6*7)+(5*4)+(4*5)+(3*5)+(2*2)+(1*3)=153
153 % 10 = 3
So 77455-23-3 is a valid CAS Registry Number.
