Check Digit Verification of cas no

The CAS Registry Mumber 85810-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,1 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85810-86:
(7*8)+(6*5)+(5*8)+(4*1)+(3*0)+(2*8)+(1*6)=152
152 % 10 = 2
So 85810-86-2 is a valid CAS Registry Number.

Efficient one-step synthesis of benzazoles in aqueous media

Boeini, Hassan Zali,Najafabadi, Khadijeh Hajibabaei

supporting information; experimental part, p. 4926 - 4929 (2010/01/18)

Benzazoles (benzoxazoles, benzothiazoles, and benzimidazoles) were efficiently prepared by the aquatic reaction of the corresponding thioamidinium salts and 2-aminophenol, 2-aminothiophenol, and 1,2-diaminobenzene, respectively. The thioamidinium salt was successfully applied as an alternative to a carboxylic acid derivative to react smoothly with an amino precursor and in the presence of catalytic amounts of hexadecyltrimethylammonium bromide salt to produce benzazoles in good to excellent yields.
