50438-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50438-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50438-40:
(7*5)+(6*0)+(5*4)+(4*3)+(3*8)+(2*4)+(1*0)=99
99 % 10 = 9
So 50438-40-9 is a valid CAS Registry Number.
