It is a derivative of the parent compound Vinpocetine, which is extracted from the lesser periwinkle plant. Impurity C is a byproduct of the manufacturing process and is typically present in trace amounts. It is important to monitor and control the levels of such impurities to ensure the safety and efficacy of the final product. The presence of impurities can affect the pharmacological activity and potential side effects of the drug, making their identification and quantification crucial in the quality control of pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 70155-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,5 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70155-05:
(7*7)+(6*0)+(5*1)+(4*5)+(3*5)+(2*0)+(1*5)=94
94 % 10 = 4
So 70155-05-4 is a valid CAS Registry Number.
