Check Digit Verification of cas no

The CAS Registry Mumber 91448-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,4 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91448-19:
(7*9)+(6*1)+(5*4)+(4*4)+(3*8)+(2*1)+(1*9)=140
140 % 10 = 0
So 91448-19-0 is a valid CAS Registry Number.

Synthesis of Lactams via Ir-Catalyzed C-H Amidation Involving Ir-Nitrene Intermediates

Li, Xiaoxun,Liu, Jitian,Tang, Weiping,Wang, Shuojin,Ye, Wenjing,Zheng, Junrong

, (2020)

x-membered lactams were synthesized via either an amidation of sp3 C-H bonds or an electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.

Evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2-imines as inhibitors of nitric oxide synthase

Shankaran,Donnelly, Karla L.,Shah, Shrenik K.,Guthikonda, Ravindra N.,MacCoss, Malcolm,Humes, John L.,Pacholok, Stephen G.,Grant, Stephan K.,Kelly,Wong

, p. 4539 - 4544 (2007/10/03)

Syntheses and evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2- imines as inhibitors of nitric oxide synthase (NOS) are discussed. An extensive SAR was established for pyrrolidin-2-imines class of compounds. The amidines came out as the most potent inhibitors in addition to displaying selectivity.
