Check Digit Verification of cas no

The CAS Registry Mumber 1245635-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,6,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1245635-41:
(9*1)+(8*2)+(7*4)+(6*5)+(5*6)+(4*3)+(3*5)+(2*4)+(1*1)=149
149 % 10 = 9
So 1245635-41-9 is a valid CAS Registry Number.

Preparation and regioselective Diels-Alder reactions of borylbenzynes: Synthesis of functionalized arylboronates

Ikawa, Takashi,Takagi, Akira,Kurita, Yurio,Saito, Kozumo,Azechi, Kenji,Egi, Masahiro,Kakiguchi, Keisuke,Kita, Yasuyuki,Akai, Shuji

, p. 5563 - 5566 (2010)

(Figure Presented) B+ [4+2]: 3-Borylbenzynes undergo Diels-Alder reactions with substituted furans and pyrroles to give highly functionalized arylboronic acid derivatives with either good or exclusive regioselectivities (see picture). The effect of the boryl group on the regioselectivity arises from electronic rather than steric effects.
