50461-20-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50461-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50461-20:
(7*5)+(6*0)+(5*4)+(4*6)+(3*1)+(2*2)+(1*0)=86
86 % 10 = 6
So 50461-20-6 is a valid CAS Registry Number.
