163881-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163881-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 163881-72:
(8*1)+(7*6)+(6*3)+(5*8)+(4*8)+(3*1)+(2*7)+(1*2)=159
159 % 10 = 9
So 163881-72-9 is a valid CAS Registry Number.

, p. 733 - 738 (2007/10/02)
α-Amino acids 1 are readily converted into the corresponding N,N-dibenzylamino aldehydes 2 which in turn serve as starting materials for enantiomerically pure α-N,N-dibenzylamino aldimines 5, 6 and 7 having benzyl, tosyl and trimethylsilyl groups, respect
