Check Digit Verification of cas no

The CAS Registry Mumber 577975-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,7,9,7 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 577975-32:
(8*5)+(7*7)+(6*7)+(5*9)+(4*7)+(3*5)+(2*3)+(1*2)=227
227 % 10 = 7
So 577975-32-7 is a valid CAS Registry Number.

5-formyl-2-furylboronic acid as a versatile bifunctional reagent for the synthesis of π-extended heteroarylfuran systems

Parry, Paul R.,Bryce, Martin R.,Tarbit, Brian

, p. 1447 - 1449 (2003)

5-Formyl-2-furylboronic acid reacts cleanly with a range of heteroaryl bromides under Suzuki-Miyaura cross-coupling conditions to produce 2-formyl-5-heteroarylfuran derivatives. Subsequent Wittig olefination reactions afford π-conjugated alkene-pyridyl-furan derivatives.
