277318-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 277318-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,3,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 277318-45:
(8*2)+(7*7)+(6*7)+(5*3)+(4*1)+(3*8)+(2*4)+(1*5)=163
163 % 10 = 3
So 277318-45-3 is a valid CAS Registry Number.
