77455-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77455-18-6 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, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77455-18:
(7*7)+(6*7)+(5*4)+(4*5)+(3*5)+(2*1)+(1*8)=156
156 % 10 = 6
So 77455-18-6 is a valid CAS Registry Number.
