Check Digit Verification of cas no

The CAS Registry Mumber 899431-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,9,4,3 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 899431-45:
(8*8)+(7*9)+(6*9)+(5*4)+(4*3)+(3*1)+(2*4)+(1*5)=229
229 % 10 = 9
So 899431-45-9 is a valid CAS Registry Number.

Conversion of Arylboronic Acids to Tetrazoles Catalyzed by ONO Pincer-Type Palladium Complex

Vignesh, Arumugam,Bhuvanesh, Nattamai S. P.,Dharmaraj, Nallasamy

, p. 887 - 892 (2018/06/15)

A convenient synthesis of a library of tetrazoles through a novel and operationally simple protocol effecting the direct conversion of arylboronic acids catalyzed by a new ONO pincer-type Pd(II) complex under mild reaction conditions using the readily available reagents is reported. The palladium complex was reused up to four cycles in an open-flask condition.

Structure-activity relationship studies on a series of novel, substituted 1-benzyl-5-phenyltetrazole P2X7 antagonists

Nelson, Derek W.,Gregg, Robert J.,Kort, Michael E.,Perez-Medrano, Arturo,Voight, Eric A.,Wang, Ying,Grayson, George,Namovic, Marian T.,Donnelly-Roberts, Diana L.,Niforatos, Wende,Honore, Prisca,Jarvis, Michael F.,Faltynek, Connie R.,Carroll, William A.

, p. 3659 - 3666 (2007/10/03)

1-Benzyl-5-aryltetrazoles were discovered to be novel antagonists for the P2X? receptor. Structure-activity relationship (SAR) studies were conducted around both the benzyl and phenyl moieties. In addition, the importance of the regiochemical substitution
