335420-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 335420-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,5,4,2 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 335420-01:
(8*3)+(7*3)+(6*5)+(5*4)+(4*2)+(3*0)+(2*0)+(1*1)=104
104 % 10 = 4
So 335420-01-4 is a valid CAS Registry Number.
