Check Digit Verification of cas no

The CAS Registry Mumber 441352-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,3,5 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 441352-22:
(8*4)+(7*4)+(6*1)+(5*3)+(4*5)+(3*2)+(2*2)+(1*2)=113
113 % 10 = 3
So 441352-22-3 is a valid CAS Registry Number.

A general strategy for the convergent synthesis of fused polycyclic ethers via B-alkyl Suzuki coupling: Synthesis of the ABCD ring fragment of ciguatoxins

Sasaki, Makoto,Ishikawa, Makoto,Fuwa, Haruhiko,Tachibana, Kazuo

, p. 1889 - 1911 (2007/10/03)

A new method for convergent coupling of fused polycyclic ethers has been developed, which relies on B-alkyl Suzuki crosscoupling of lactone-derived enol triflates or phosphates. The strategy was successfully applied to a convergent synthesis of the ABCD r
