78304-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78304-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,0 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78304-49:
(7*7)+(6*8)+(5*3)+(4*0)+(3*4)+(2*4)+(1*9)=141
141 % 10 = 1
So 78304-49-1 is a valid CAS Registry Number.
