127299-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127299-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,9 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127299-57:
(8*1)+(7*2)+(6*7)+(5*2)+(4*9)+(3*9)+(2*5)+(1*7)=154
154 % 10 = 4
So 127299-57-4 is a valid CAS Registry Number.

Acyliminium cyclization of several chiral N-alkenylsuccinimide derivatives
Ohwada,Inouye,Kimura,Kakisawa
, p. 287 - 289 (2007/10/02)
The acyliminium intermediate derived from (3R,4R)-N-(3-butenyl)-3,4-bis(benzyloxy)succinimide cyclized to give (8aS)- and (8aR)-hexahydro-3(2H)-indolidinone derivatives. On the other hand, those derived from N-3-hexenyl derivatives afforded (8aS)-hexahydr
