Check Digit Verification of cas no

The CAS Registry Mumber 950511-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,0,5,1 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 950511-23:
(8*9)+(7*5)+(6*0)+(5*5)+(4*1)+(3*1)+(2*2)+(1*3)=146
146 % 10 = 6
So 950511-23-6 is a valid CAS Registry Number.

Differentially protected benzenediboronic acids: Divalent cross-coupling modules for the efficient synthesis of boron-substituted oligoarenes

Noguchi, Hiroyoshi,Shioda, Takayuki,Chou, Chih-Ming,Suginome, Michinori

, p. 377 - 380 (2008/09/19)

On the basis of the boron-masking strategy, new divalent cross-coupling modules have been designed for the efficient synthesis of boronsubstituted oligoarenes. The modules, i.e., monoprotected o-, m-, and p-benzenediboronic acid derivatives, undergo highly selective SuzukiMiyaura coupling with sp 2 iodides, bromides, chlorides, and triflates, affording coupling products in which the protected boronyl groups are left intact.
