Check Digit Verification of cas no

The CAS Registry Mumber 90921-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90921-53:
(7*9)+(6*0)+(5*9)+(4*2)+(3*1)+(2*5)+(1*3)=132
132 % 10 = 2
So 90921-53-2 is a valid CAS Registry Number.

[NO3], a green and base-free medium for one-pot synthesis of benzothiazinones at room temperature

Sharifi, Ali,Abaee, M. Saeed,Rouzgard, Mahdiyeh,Mirzaei, Mojtaba

, p. 2079 - 2089 (2013/06/26)

A general and efficient room-temperature procedure is developed for high-yield synthesis of 2H-benzo[b][1,4]thiazin-3(4H)-one derivatives in one pot from the reaction of 2-aminothiophenols with 2-bromoalkanoates in ionic liquid [bmim]NO3 without the use of any catalyst, base, or additive. Products were obtained in good yields by simple extraction with Et2O followed by evaporation of the volatile contents and recrystallization from Et2O. The ionic liquid was recycled and reused in the next reaction without the loss of its activity.
