157060-06-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157060-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,6 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157060-06:
(8*1)+(7*5)+(6*7)+(5*0)+(4*6)+(3*0)+(2*0)+(1*6)=115
115 % 10 = 5
So 157060-06-5 is a valid CAS Registry Number.

Preparation of optically active succinic acid derivatives. II. Efficient and practical synthesis of KAD-1229

Yamaguchi, Toshiaki,Yanagi, Takashi,Hokari, Hiroshi,Mukaiyama, Yuko,Kamijo, Tetsuhide,Yamamoto, Iwao

, p. 337 - 340 (2007/10/03)

For large-scale synthesis of monocalcium bis[(2s)-2-benzyl-3-(cis- hexahydroisoindolin-2-ylcarbonyl)propionate]dihydrate (1, KAD-1229), we investigated regioselective reactions of (S)-2-benzylsuccinic acid (2) with cis-hexahydroisoindoline (4). It was difficult to obtain a half amide regioselectively through coupling reaction of the (S)-acid 2 with the amine 4. Therefore, the succinic acid 2 was converted to bis-activated esters 3a-c and these were reacted with 4 to give the amides 5a-c in good yields, regioselectively. The amides 5a-c were derived to KAD-1229, which has a potent hypoglycemic effect, in good yields.
