6334-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6334-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,3 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6334-91:
(6*6)+(5*3)+(4*3)+(3*4)+(2*9)+(1*1)=94
94 % 10 = 4
So 6334-91-4 is a valid CAS Registry Number.
