304478-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 304478-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,4,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 304478-23:
(8*3)+(7*0)+(6*4)+(5*4)+(4*7)+(3*8)+(2*2)+(1*3)=127
127 % 10 = 7
So 304478-23-7 is a valid CAS Registry Number.
