Check Digit Verification of cas no

The CAS Registry Mumber 701975-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,1,9,7 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 701975-71:
(8*7)+(7*0)+(6*1)+(5*9)+(4*7)+(3*5)+(2*7)+(1*1)=165
165 % 10 = 5
So 701975-71-5 is a valid CAS Registry Number.

Imino 1,2-Wittig rearrangement of hydroximates and its application to synthesis of cytoxazone

Miyata, Okiko,Koizumi, Tomoko,Asai, Hiroshi,Iba, Ryuichi,Naito, Takeaki

, p. 3893 - 3914 (2007/10/03)

The imino 1,2-Wittig rearrangement of hydroximates provides a novel method for the construction of 2-hydroxyoxime ethers. Upon treatment with LDA, Z-hydroximates smoothly underwent stereoselective rearrangement to give Z-2-hydroxyoxime ethers in good yield, which were converted into amino alcohols. On the other hand, the rearrangement of E-hydroximates gave a mixture of E- and Z-2-hydroxyoxime ethers. This method was successfully applied to a practical synthesis of cytoxazone.
