Check Digit Verification of cas no
The CAS Registry Mumber 350691-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,6,9 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 350691-09:
(8*3)+(7*5)+(6*0)+(5*6)+(4*9)+(3*1)+(2*0)+(1*9)=137
137 % 10 = 7
So 350691-09-7 is a valid CAS Registry Number.

A rapid access to coumarin derivatives (using Vilsmeier-Haack and Suzuki cross-coupling reactions)
Hesse, Stéphanie,Kirsch, Gilbert
, p. 1213 - 1215 (2007/10/03)
A four-step preparation of compounds containing a coumarinic moiety is presented. This synthesis involves notably a Suzuki cross-coupling reaction (performed in aqueous media) and a ring closure by formation of δ-lactone.
