635714-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 635714-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,5,7,1 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 635714-19:
(8*6)+(7*3)+(6*5)+(5*7)+(4*1)+(3*4)+(2*1)+(1*9)=161
161 % 10 = 1
So 635714-19-1 is a valid CAS Registry Number.

A concise synthesis of the HCV protease inhibitor BILN 2061 and its P3 modified analogs

Liu, Dejun,Dong, Jingchao,Yin, Yunxing,Ma, Rujian,Shi, Yifeng,Wu, Hao,Chen, Shuhui,Li, Ge

experimental part, p. 1489 - 1502 (2011/11/01)

A concise synthesis of BILN 2061 was achieved through more efficient installation of P2 4-quinoline moiety via SN2 displacement of the β-OBs group located on the 4-hydroxyl proline intermediate, which was prepared from 4-α-hydroxyl proline analog via Mitsunobu reaction with inversion of stereochemistry. In addition, a short and practical synthesis for P3 unit is also described herein. Final assembly of four fragments for BILN 2061 was achieved with an overall yield of 58% in 4 steps from P1 to 15a. Furthermore several analogs of BILN 2061 (WX-1-WX-5) containing modifications on P3 unit were synthesized successfully using the same synthetic route as described for the parent inhibitor BILN 2061.
