Check Digit Verification of cas no

The CAS Registry Mumber 70738-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,3 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70738-05:
(7*7)+(6*0)+(5*7)+(4*3)+(3*8)+(2*0)+(1*5)=125
125 % 10 = 5
So 70738-05-5 is a valid CAS Registry Number.

Total Synthesis of Frustulosin and Aurocitrin

Ronald, Robert C.,Lansinger, Janet M.,Lillie, Thomas S.,Wheeler, Carl J.

, p. 2541 - 2549 (2007/10/02)

The regioselective total syntheses of the novel fungal antibiotics frustulosin (1) and aurocitrin (2) were accomplished from 3,6-dihydroxy-2-iodobenzaldehyde (10) which was prepared by a regiodirected metalation of 2,5-dimethylbenzyl vinyl ether to establish the 1,2,3,4-tetrasubstitution pattern of these compounds.The unsaturated side chains of these hydroquinone antibiotics were attached by using the iodo aldehyde functionalities.The structures of these antibiotics are confirmed by synthesis.
