442528-06-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442528-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,5,2 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 442528-06:
(8*4)+(7*4)+(6*2)+(5*5)+(4*2)+(3*8)+(2*0)+(1*6)=135
135 % 10 = 5
So 442528-06-5 is a valid CAS Registry Number.

Studies toward the total synthesis of RP-66453
Boisnard, Sabine,Zhu, Jieping
, p. 2577 - 2580 (2007/10/03)
Synthesis of a bicyclic A-B-O-C ring system of RP-66453, an neurotensine receptor antagonist, with an endo aryl-aryl and an endo aryl-aryl ether bond is described. An alternative synthetic strategy starting from the construction of functionalized B-O-C cycloisodityrosine unit is also detailed.
