304462-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 304462-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,4,6 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 304462-49:
(8*3)+(7*0)+(6*4)+(5*4)+(4*6)+(3*2)+(2*4)+(1*9)=115
115 % 10 = 5
So 304462-49-5 is a valid CAS Registry Number.
