809274-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 809274-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,9,2,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 809274-72:
(8*8)+(7*0)+(6*9)+(5*2)+(4*7)+(3*4)+(2*7)+(1*2)=184
184 % 10 = 4
So 809274-72-4 is a valid CAS Registry Number.
