642-04-6 Usage


2,3,5,6-Tetraphenylpyrazine exhibits antidiabetic activity in sucrose-loaded and streptozotocin-induced diabetic rat models.

Check Digit Verification of cas no

The CAS Registry Mumber 642-04-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 642-04:
56 % 10 = 6
So 642-04-6 is a valid CAS Registry Number.
