Check Digit Verification of cas no

The CAS Registry Mumber 491872-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 491872-92:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*2)+(2*9)+(1*2)=195
195 % 10 = 5
So 491872-92-5 is a valid CAS Registry Number.

Synthesis of triazolyl-oxadiazolyl-thiazolyl- and thiadiazolylbenzofuran of potential biological activity

Atta,Fawzy,Ahmed,Abdel-Rahman

, p. 863 - 875 (2002)

4,7-Dimethoxy (Ia) and 4-methoxy (Ib) 6-hydroxybenzofuran-5-carbohydrazide were reacted with aryl or alkyl isothiocyanates to give the corresponding thiosemicarbazides (IIa-h). Cyclization of the substituted thiosemicarbazides with sodium hydroxide led to the formation of 1,3,4-triazol-2-yl-benzofuran derivatives (IIIa-d). Desulfurization of thiosemicarbazide by mercuric oxide gave 1,3,4-oxadiazolyl-benzofuran (IVa-c). Treatment of thiosemicarbazide with ethyl bromo-acetate or α-bromopropionic acid yielded 4-thiazolidin-2-yl-carbonyl-benzofuran (Va-h). The reaction of compounds IIb,e,f with sulphuric acid or phosphorus oxychloride gave 1,3,4-thiadiazol-2-yl-benzofuran (VIa-d, VII).
