Check Digit Verification of cas no

The CAS Registry Mumber 452056-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 452056-87:
(8*4)+(7*5)+(6*2)+(5*0)+(4*5)+(3*6)+(2*8)+(1*7)=140
140 % 10 = 0
So 452056-87-0 is a valid CAS Registry Number.

Tri- and tetrasubstituted imidazoles as p38α mitogen-activated protein kinase inhibitors

Laufer, Stefan,Hauser, Dominik,Stegmiller, Thomas,Bracht, Claudia,Ruff, Kathrin,Schattel, Verena,Albrecht, Wolfgang,Koch, Pierre

scheme or table, p. 6671 - 6675 (2010/12/19)

The synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles as potent p38α mitogen-activated protein kinase inhibitors is described. The trisubstituted imidazole series was found to be more potent than the tetrasubstituted imidazole seri

Tetrasubstituted imidazole inhibitors of cytokine release: Probing substituents in the N-1 position

Laufer, Stefan A.,Zimmermann, Werner,Ruff, Kathrin J.

, p. 6311 - 6325 (2007/10/03)

We prepared novel 1,2,4,5-tetrasubstituted imidazole derivatives with high anti-inflammatory activity by using our previously described regiospecific synthesis. Systematic optimization of the imidazole N-1 substituent resulted in compound 9b that potently
