Check Digit Verification of cas no

The CAS Registry Mumber 1570158-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,0,1,5 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1570158-28:
(9*1)+(8*5)+(7*7)+(6*0)+(5*1)+(4*5)+(3*8)+(2*2)+(1*8)=159
159 % 10 = 9
So 1570158-28-9 is a valid CAS Registry Number.

Biomimetic total synthesis of (±)-doitunggarcinone A and (+)-garcibracteatone

Pepper, Henry P.,Tulip, Stephen J.,Nakano, Yuji,George, Jonathan H.

, p. 2564 - 2573 (2014/04/17)

A full account of our oxidative radical cyclization approach to the synthesis of garcibracteatone and doitunggarcinone A is presented. This includes the first enantioselective synthesis of garcibracteatone, which allowed the absolute configuration of the natural compound to be determined. The first synthesis of doitunggarcinone A is also described, which confirms our reassignment of the relative configuration of this molecule. Novel syntheses of monoterpene fragments used to construct the target molecules are also reported.
