4190-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4190-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4190-80:
(6*4)+(5*1)+(4*9)+(3*0)+(2*8)+(1*0)=81
81 % 10 = 1
So 4190-80-1 is a valid CAS Registry Number.
