515844-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 515844-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,5,8,4 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 515844-80:
(8*5)+(7*1)+(6*5)+(5*8)+(4*4)+(3*4)+(2*8)+(1*0)=161
161 % 10 = 1
So 515844-80-1 is a valid CAS Registry Number.
