Check Digit Verification of cas no

The CAS Registry Mumber 1323158-79-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,3,1,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1323158-79:
(9*1)+(8*3)+(7*2)+(6*3)+(5*1)+(4*5)+(3*8)+(2*7)+(1*9)=137
137 % 10 = 7
So 1323158-79-7 is a valid CAS Registry Number.

Merging the ring opening of benzoxazoles with secondary amines and an iron-catalyzed oxidative cyclization towards the environmentally friendly synthesis of 2-aminobenzoxazoles

Xu, Daqian,Wang, Wenfang,Miao, Chengxia,Zhang, Qiaohong,Xia, Chungu,Sun, Wei

, p. 2975 - 2980 (2013/10/08)

A facile and environmentally friendly method was developed through merging the ring opening of benzoxazoles with secondary amines and an iron-catalyzed oxidative cyclization towards the synthesis of 2-aminobenzoxazoles. In the oxidative cyclization step, with catalytic amounts of FeCl and aqueous H 2O2 as a green oxidant, highly desirable 2-aminobenzoxazoles were isolated in excellent yields of up to 97%. A plausible radical process is proposed for the oxidative cyclization on the basis of mechanistic studies.
