Check Digit Verification of cas no

The CAS Registry Mumber 1338361-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,6 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1338361-32:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*6)+(3*1)+(2*3)+(1*2)=152
152 % 10 = 2
So 1338361-32-2 is a valid CAS Registry Number.

Three series of novel 1H-1,2,3-triazole-4-carboxamides: 1-aryl-5-alkyl/aryl-1H-1,2,3-triazole-4-carboxamides, 1-aryl-5-amino-1H-1,2,3-triazole-4-carboxamides and 1,2,3-triazolo[1,5-a]quinazoline-3-carboxamides were synthesized via base-mediated click azide reactions. Compounds were evaluated for their antimicrobial activities against primary pathogens: Gram-positive and Gram-negative bacterial strains Escherichia coli, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, as well as fungal strain Cryptococcus neoformans var. grubii and Candida albicans. Compounds exhibiting moderate to good activities were selected for SAR analysis. Several 5-methyl-1H-1,2,3-triazole-4-carboxamides 4d, 4l, 4r, showed potent antibacterial effect against S. aureus. On the contrary, 5-amino-1H-1,2,3-triazole-4-carboxamide 8b and [1,2,3]triazolo[1,5-a]quinazoline-3-carboxamide 9a were active against pathogenic yeast C. albicans. Thus, compound 4l under 1 μM demonstrated 50% growth inhibition against S. aureus. At the same concentration, the compound 9a killed approx. 40% of C. albicans cells. In general, these compounds demonstrated selective action and no significant impact on the viability of human keratinocytes of HaCaT line.
