Check Digit Verification of cas no

The CAS Registry Mumber 1257429-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257429-40:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*2)+(3*9)+(2*4)+(1*0)=165
165 % 10 = 5
So 1257429-40-5 is a valid CAS Registry Number.

Efficient synthesis of novel 1,2,4-triazole fused acyclic and 21-28 membered macrocyclic and/or lariat macrocyclic oxaazathia crown compounds with potential antimicrobial activity

Khalil, Nasser S.A.M.

experimental part, p. 5265 - 5277 (2011/01/04)

Versatile simple efficient routes with good to excellent yields towards different functionalized 1,ω-bis(1,2,4-triazoles), 21-28 membered 1,2,4-triazole fused macrocyclic and/or lariat macrocyclic oxaazathia crown Schiff bases and/or amines have been investigated. Antimicrobial screening of some selected compounds revealed different inhibitory effects against Aspergillus fumigatus RCMB 002008 (1), Penicillium italicum RCMB 001018 (1), Syncephalastrum racemosum RCMB 016001 Candida albicans RCMB 005003, Staphylococcus aureus RCMB 106-001 (1), Pseudomonas aeruginosa RCMB 102-002, Bacillus subtilis RCMB 101-001 and Escherichia coli RCMB 103-001.
