134679-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134679-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,7 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134679-67:
(8*1)+(7*3)+(6*4)+(5*6)+(4*7)+(3*9)+(2*6)+(1*7)=157
157 % 10 = 7
So 134679-67-7 is a valid CAS Registry Number.

The asymmetric synthesis of β-lactam antibiotics. I. Application of chiral oxazolidones in the Staudinger Reaction
Evans,Sjogren
, p. 3783 - 3786 (2007/10/02)
The reactions of oxazolidone with N-benzylimines proceed with exceptional levels of asymmetric induction to form the cycloadducts. Subsequent dissolving metal reduction affords the homochiral β-lactam derivatives in good overall yield.
