167983-27-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167983-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,9,8 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167983-27:
(8*1)+(7*6)+(6*7)+(5*9)+(4*8)+(3*3)+(2*2)+(1*7)=189
189 % 10 = 9
So 167983-27-9 is a valid CAS Registry Number.

Design, synthesis, activity, and structure of a novel class of matrix metalloproteinase inhibitors containing a heterocyclic P'2-P'3 amide bond isostere

Chen, Jian Jeffrey,Zhang, Yiping,Hammond, Scott,Dewdney, Nolan,Ho, Teresa,Lin, Xiaohong,Browner, Michelle F.,Castelhano, Arlindo L.

, p. 1601 - 1606 (2007/10/03)

A novel series of hydroxamate-based inhibitors of matrix metalloproteinases containing benzimidazole and imidazole heterocycles as amide bond isosteres have been prepared. Potent inhibition (in the low nanomolar range) and selectivity (> 100-fold) can be attained with inhibitors containing only one amide bond. X-ray crystal structures of matrilysin (MMP- 7) with two different inhibitors bound confirm that imidazole is an excellent amide bond isostere.
