437768-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 437768-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,7,6 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 437768-39:
(8*4)+(7*3)+(6*7)+(5*7)+(4*6)+(3*8)+(2*3)+(1*9)=193
193 % 10 = 3
So 437768-39-3 is a valid CAS Registry Number.

Novel thiazolones as HCV NS5B polymerase allosteric inhibitors: Further designs, SAR, and X-ray complex structure

Yan, Shunqi,Larson, Gary,Wu, Jim Z.,Appleby, Todd,Ding, Yili,Hamatake, Robert,Hong, Zhi,Yao, Nanhua

, p. 63 - 67 (2007/10/03)

Structure-activity relationships (SAR) of 1 against HCV NS5B polymerase were described. SAR explorations and further structure-based design led to the identifications of 2 and 3 as novel HCV NS5B inhibitors. X-ray structure of 3 in complex with NS5B polymerase was obtained at a resolution of 2.2 A, and confirmed the design.

An expedient route to the tetrazole analogues of α-amino acids

Demko, Zachary P.,Sharpless, K. Barry

, p. 2525 - 2527 (2007/10/03)

(Matrix presented) Convenient conditions are described for the transformation of α-aminonitriles to the tetrazole analogues of α-amino acids. Refluxing the starting material in water/2-propanol at 80 °C with sodium azide and catalytic zinc bromide affords
