857664-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857664-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,6,6 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 857664-99:
(8*8)+(7*5)+(6*7)+(5*6)+(4*6)+(3*4)+(2*9)+(1*9)=234
234 % 10 = 4
So 857664-99-4 is a valid CAS Registry Number.

Hydroxyl may not be indispensable for raltegravir: Design, synthesis and SAR Studies of raltegravir derivatives as HIV-1 inhibitors

, p. 361 - 369 (2012/06/30)

A series of raltegravir derivatives 20-42 were prepared and systematically evaluated for their anti-HIV activity. The bioassay results showed that most of the compounds possess good to excellent anti-HIV activity. Especially, compounds 25 and 35 with subpicomole IC50 values seemed to be the most potent anti-HIV agents among all of the reported synthesized compounds. These compounds may therefore be considered as new potent anti-HIV agents. The 5-hydroxyl modification of raltegravir derivatives significantly increased the anti-HIV activity, which indicates that the hydroxyl may not be indispensable for raltegravir. The introducing of acyl at 5-position of raltegravir derivatives is favorable for antiviral activity. In addition, a high-throughput cell-based assay method with pseudotyped virus stocks was developed and used to identify HIV inhibitors.
