1339022-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1339022-13-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,9,0,2 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1339022-13:
(9*1)+(8*3)+(7*3)+(6*9)+(5*0)+(4*2)+(3*2)+(2*1)+(1*3)=127
127 % 10 = 7
So 1339022-13-7 is a valid CAS Registry Number.

Synthesis of NP25302
Stevens, Kiri,Tyrrell, Andrew J.,Skerratt, Sarah,Robertson, Jeremy
, p. 5964 - 5967 (2011)
An efficient synthesis of NP25302 is presented that relies on 5-endo-dig N-cyclization to establish the bicyclic core and Curtius rearrangement to install the N-acyl vinylogous urea functionality.
