Check Digit Verification of cas no

The CAS Registry Mumber 142929-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,2 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142929-23:
(8*1)+(7*4)+(6*2)+(5*9)+(4*2)+(3*9)+(2*2)+(1*3)=135
135 % 10 = 5
So 142929-23-5 is a valid CAS Registry Number.

Visible-Light-Driven Synthesis of Arylstannanes from Arylazo Sulfones

Lian, Chang,Yue, Guanglu,Mao, Jinshan,Liu, Danyang,Ding, Yi,Liu, Zerong,Qiu, Di,Zhao, Xia,Lu, Kui,Fagnoni, Maurizio,Protti, Stefano

, p. 5187 - 5191 (2019)

The visible-light-driven preparation of (hetero)aryl stannanes was carried out under both photocatalyst- and metal-free conditions via irradiation of arylazo sulfones in the presence of hexaalkyldistannanes. The reaction shows a high efficiency and a wide substrates scope. The resulting crude organotin derivatives can be directly employed in a Stille protocol.
