247095-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247095-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,9 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 247095-97:
(8*2)+(7*4)+(6*7)+(5*0)+(4*9)+(3*5)+(2*9)+(1*7)=162
162 % 10 = 2
So 247095-97-2 is a valid CAS Registry Number.
