Check Digit Verification of cas no

The CAS Registry Mumber 862254-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,2,5 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 862254-91:
(8*8)+(7*6)+(6*2)+(5*2)+(4*5)+(3*4)+(2*9)+(1*1)=179
179 % 10 = 9
So 862254-91-9 is a valid CAS Registry Number.

Inter- and intramolecular Mitsunobu reaction based approaches to 2-substituted chromans and chroman-4-ones

Hodgetts, Kevin J.

, p. 6860 - 6870 (2007/10/03)

Two approaches to optically active 2-substituted chromans and chroman-4-ones are described. The first utilized an intermolecular Mitsunobu reaction of a homochiral halopropanol and 2-bromophenol followed by cyclization to the 2-substituted chroman. In addition, a double lithiation procedure was developed to introduce additional functionality to the chroman. The second approach utilized an intramolecular Mitsunobu cyclization to give the 2-substituted chroman-4-one nucleus. The methodologies were applied to the syntheses of several biologically active natural and synthetic products.
