743472-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 743472-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,3,4,7 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 743472-16:
(8*7)+(7*4)+(6*3)+(5*4)+(4*7)+(3*2)+(2*1)+(1*6)=164
164 % 10 = 4
So 743472-16-4 is a valid CAS Registry Number.

Short synthesis of the 6,6-spiroketal cores of spirofungins A and B
Dias, Luiz C.,De Oliveira, Luciana G.
, p. 2587 - 2590 (2007/10/03)
(Matrix Presented) Initial efforts toward the total synthesis of the antifungal antibiotics spirofungins A and B are reported. A short and efficient synthesis of the C9-C20 6,6-spiroketal fragments of both compounds is described. This asymmetric approach
