Check Digit Verification of cas no

The CAS Registry Mumber 1140903-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,9,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1140903-18:
(9*1)+(8*1)+(7*4)+(6*0)+(5*9)+(4*0)+(3*3)+(2*1)+(1*8)=109
109 % 10 = 9
So 1140903-18-9 is a valid CAS Registry Number.

Access to functionalized isoquinoline N-oxides via sequential electrophilic cyclization/cross-coupling reactions

Ding, Qiuping,Wu, Jie

, p. 1850 - 1854 (2008)

Electrophilic cyclization of 2-alkynylbenzaldoximes with various electrophiles leads to the formation of 4-iodoisoquinoline N-oxides or 4-bromo-isoquinoline N-oxides under mild conditions. The reaction can be transferred to highly functionalized isoquinol
