27904-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27904-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,0 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27904-56:
(7*2)+(6*7)+(5*9)+(4*0)+(3*4)+(2*5)+(1*6)=129
129 % 10 = 9
So 27904-56-9 is a valid CAS Registry Number.
