141804-54-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141804-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,0 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141804-54:
(8*1)+(7*4)+(6*1)+(5*8)+(4*0)+(3*4)+(2*5)+(1*4)=108
108 % 10 = 8
So 141804-54-8 is a valid CAS Registry Number.
