77868-41-8 Usage
Uses
Used in Medical Imaging Industry:DesMethyl IopaMidol is used as an impurity in the synthesis of Iopamidol, which serves as a radiopaque medium for diagnostic imaging purposes. Iopamidol enhances the visibility of internal structures during X-ray, CT, and other imaging procedures, allowing for accurate diagnosis and treatment planning. The presence of DesMethyl IopaMidol in the synthesis process is crucial for the development of effective and safe radiocontrast agents.
Check Digit Verification of cas no
The CAS Registry Mumber 77868-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.Calculate Digit Verification of CAS Registry Number 77868-41:
(7*7)+(6*7)+(5*8)+(4*6)+(3*8)+(2*4)+(1*1)=188
188 % 10 = 8
So 77868-41-8 is a valid CAS Registry Number.
