Check Digit Verification of cas no

The CAS Registry Mumber 1121703-21-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,1,7,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1121703-21:
(9*1)+(8*1)+(7*2)+(6*1)+(5*7)+(4*0)+(3*3)+(2*2)+(1*1)=86
86 % 10 = 6
So 1121703-21-6 is a valid CAS Registry Number.

Design and synthesis of 4-aryl-4-oxobutanoic acid amides as calpain inhibitors

scheme or table, p. 502 - 507 (2011/02/28)

The involvement of μ-calpain in neurological disorders, such as stroke and Alzheimer's disease has attracted considerable interest in the use of calpain inhibitors as therapeutic agents. 4-Aryl-4-oxobutanoic acid amide derivatives 4 were designed as acyclic variants of μ-calpain inhibitory chromone and quinolinone derivatives. Of the compounds synthesized, 4c-2, which possesses a 2-methoxymethoxy group at the phenyl ring and a primary amide at the warhead region most potently inhibited μ-calpain (IC50 = 0.34 μM). Our findings suggest that the 4-aryl-4-oxobutanoic acid amide derivatives should be considered as a new family of μ-calpain inhibitors.
