55215-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55215-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,1 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55215-32:
(7*5)+(6*5)+(5*2)+(4*1)+(3*5)+(2*3)+(1*2)=102
102 % 10 = 2
So 55215-32-2 is a valid CAS Registry Number.

Functionalization of diazotetronic acid and application in a stereoselective modular synthesis of pulvinone, aspulvinones A-E, G, Q and their analogues

Manchoju, Amarender,Annadate, Ritesh A.,Desquien, Lise,Pansare, Sunil V.

, p. 6224 - 6238 (2018/09/10)

A modular synthesis of aspulvinones A, B, C, D, E, G and the recently isolated aspulvinone Q was developed. The methodology features a highly stereoselective aldol condensation of diazotetronic acid with aldehydes to provide 5-arylidene diazotetronates. S
