134872-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134872-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,7 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134872-89:
(8*1)+(7*3)+(6*4)+(5*8)+(4*7)+(3*2)+(2*8)+(1*9)=152
152 % 10 = 2
So 134872-89-2 is a valid CAS Registry Number.

Development of chiral stabilised azomethine ylids: A chiral memory relay system
Anslow,Harwood,Phillips,Watkin,Wong
, p. 1343 - 1358 (1991)
Chiral, stabilised azomethine ylids incorporated in cyclic templates derived from (R)- or (S)-2-phenylglycinol and (S)-valine undergo enantioselective 1,3-dipolar cycloaddition reactions with a variety of dipolarophiles. Removal of the template in the cas
