108401-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108401-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,0 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108401-50:
(8*1)+(7*0)+(6*8)+(5*4)+(4*0)+(3*1)+(2*5)+(1*0)=89
89 % 10 = 9
So 108401-50-9 is a valid CAS Registry Number.
