Check Digit Verification of cas no

The CAS Registry Mumber 58809-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58809-90:
(7*5)+(6*8)+(5*8)+(4*0)+(3*9)+(2*9)+(1*0)=168
168 % 10 = 8
So 58809-90-8 is a valid CAS Registry Number.

Diversity-Oriented Synthesis of 1,2,4-Triazols, 1,3,4-Thiadiazols, and 1,3,4-Selenadiazoles from N-Tosylhydrazones

Wei, Zeyang,Zhang, Qi,Tang, Meng,Zhang, Siyu,Zhang, Qian

supporting information, p. 4436 - 4440 (2021/05/26)

The diversity-oriented synthesis of 1,2,4-triazols, 1,3,4-thiadiazols, and 1,3,4-selenadiazoles from N-tosylhydrazones was developed, and the reactions were general for a wide range of substrates, in which NH2CN, KOCN, KSCN, and KSeCN were used as odorless sources. Two different pathways were proposed, and N-tosylhydrazonoyl chlorides were formed in situ in the presence of NCS.

Acid-Promoted [3 + 1 + 1] Cyclization of N-Tosylhydrazones and Isocyanides: A Method for the Preparation of 4,5-Diaminopyrazoles

Zhang, Qian,Tang, Meng,Zhang, Siyu,Wei, Zeyang

supporting information, p. 5182 - 5186 (2020/07/04)

A facile method for the preparation of 4,5-diaminopyrazoles from N-tosylhydrazones and isocyanides was developed. The reaction was general for a wide range of substrates, and it demonstrated excellent tolerance to a variety of substituents. More important

A chiral squaramide-catalyzed asymmetric dearomative tandem annulation reaction through a kinetic resolution of MBH alcohols: Highly enantioselective synthesis of three-dimensional heterocyclic compounds

Zhou, Leijie,Zeng, Yuan,Gao, Xing,Wang, Qijun,Wang, Chang,Wang, Bo,Wang, Wei,Wu, Yongjun,Zheng, Bing,Guo, Hongchao

supporting information, p. 10464 - 10467 (2019/09/07)

In this communication, a chiral squaramide-catalyzed asymmetric dearomative tandem annulation reaction of unmodified Morita-Baylis-Hillman alcohols with azomethine imines has been achieved through a kinetic resolution of MBH alcohols under mild conditions
