The CAS Registry Mumber 1603885-47-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,3,8,8 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1603885-47:
(9*1)+(8*6)+(7*0)+(6*3)+(5*8)+(4*8)+(3*5)+(2*4)+(1*7)=177
177 % 10 = 7
So 1603885-47-7 is a valid CAS Registry Number.

First enantioselective total synthesis of penicimarin B, aspergillumarins A and B

Yadav, Jhillu Singh,Mishra, Anand Kumar,Dachavaram, Soma Shekar,Ganesh Kumar,Das, Saibal

, p. 2921 - 2923 (2014)

A convergent enantioselective synthesis of penicimarin B, aspergillumarin A and B has been reported using Brown's allylation, DeBrabander-Bhattacharjee lactonization and Grubbs cross coupling metathesis. During this synthesis we have standardized the conditions for DeBrabande-Bhattacharjee lactonization to obtain excellent yield (>90%).
