135138-42-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135138-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135138-42:
(8*1)+(7*3)+(6*5)+(5*1)+(4*3)+(3*8)+(2*4)+(1*2)=110
110 % 10 = 0
So 135138-42-0 is a valid CAS Registry Number.

A cycloaddition approach to breynolide

Martin, Stephen F.,Anderson, Bruce G.,Daniel, Dilon,Gaucher, Anne

, p. 8997 - 9006 (2007/10/03)

A novel approach to the functionalized hydrobenzothiophene subunit of the sesquiterpene breynolide (3) has been developed. The sequence features the Diels-Alder reaction of the vinyl sulfones 12 and 13 with the Danishefsky diene 9 to give the cycloadducts 14 and 16 as the major products. Reduction of the sulfone moieties of 14 and 16 gave the sulfides 20 and 21, respectively. Subsequent dipolar cycloaddition of 20 and 21 with a functionalized nitrile oxide gave the corresponding adducts 24 and 25, which possess functionality suitable for elaboration into breynolide (3).

A novel approach to breynolide

Martin,Daniel

, p. 4281 - 4284 (2007/10/02)

The viability of the key steps in our approach to the novel sesquiterpene breynolide (1) has been verified by preparation of the hydrobenzothiophene 16. The sequence features a Diels-Alder reaction of 10 with 7 to lead eventually to 13; subsequent dipolar
