334946-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 334946-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,9,4 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 334946-80:
(8*3)+(7*3)+(6*4)+(5*9)+(4*4)+(3*6)+(2*8)+(1*0)=164
164 % 10 = 4
So 334946-80-4 is a valid CAS Registry Number.
