83807-51-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83807-51-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,0 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83807-51:
(7*8)+(6*3)+(5*8)+(4*0)+(3*7)+(2*5)+(1*1)=146
146 % 10 = 6
So 83807-51-6 is a valid CAS Registry Number.
