Check Digit Verification of cas no

The CAS Registry Mumber 1156544-15-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,6,5,4 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1156544-15:
(9*1)+(8*1)+(7*5)+(6*6)+(5*5)+(4*4)+(3*4)+(2*1)+(1*5)=148
148 % 10 = 8
So 1156544-15-8 is a valid CAS Registry Number.

Light-induced synthesis of π-extended tetrathiafulvalenes incorporating ferrocenes: An efficient route for the synthesis of electron-donor materials

Sarhan, Abdelwareth A. O.,Bolma, Carsten

experimental part, p. 1000 - 1006 (2009/12/01)

A new method for the synthesis of π-extended tetrathiafulvalenes was developed. The protocol is based on the exposure of 1,4-dithiafulvenes to sunlight or UV light at ambient temperature. In the resulting chalcogenofulvalenes the 1,3-dithiole ring systems are separated by conjugated spacers. Extended TTF analogues are obtained by insertion of linear π-conjugated spacers (C=C-C=C) of increasing dimensions between the two 1,4-dithiafulvenyl moieties. Georg Thieme Verlag Stuttgart.
