6683-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6683-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6683-74:
(6*6)+(5*6)+(4*8)+(3*3)+(2*7)+(1*4)=125
125 % 10 = 5
So 6683-74-5 is a valid CAS Registry Number.
