4335-84-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4335-84-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.Calculate Digit Verification of CAS Registry Number 4335-84:
(6*4)+(5*3)+(4*3)+(3*5)+(2*8)+(1*4)=86
86 % 10 = 6
So 4335-84-6 is a valid CAS Registry Number.
