Check Digit Verification of cas no

The CAS Registry Mumber 145654-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,5 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145654-82:
(8*1)+(7*4)+(6*5)+(5*6)+(4*5)+(3*4)+(2*8)+(1*2)=146
146 % 10 = 6
So 145654-82-6 is a valid CAS Registry Number.

A simple way to sequentially connected polycycles containing terminal pyrrole rings: Synthesis of possible precursors of materials for nonlinear optics

Lucchesini, Francesco

, p. 9951 - 9966 (2007/10/02)

the readily available 1,3-dioxolane-2-propanal allows the transformation of aromatic and heteroaromatic mono and dilithioderivatives into polycycles containing one or two pyrrole rings. Organolithiums bearing electron acceptor groups can be also employed affording possible precursors of materials for nonlinear optics.
