5819-34-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5819-34-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.Calculate Digit Verification of CAS Registry Number 5819-34:
(6*5)+(5*8)+(4*1)+(3*9)+(2*3)+(1*4)=111
111 % 10 = 1
So 5819-34-1 is a valid CAS Registry Number.
