121129-32-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121129-32-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,2 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121129-32:
(8*1)+(7*2)+(6*1)+(5*1)+(4*2)+(3*9)+(2*3)+(1*2)=76
76 % 10 = 6
So 121129-32-6 is a valid CAS Registry Number.

ASYMMETRIC INDUCTION IN THE DIELS-ALDER REACTIONS OF α-HYDROXYACYLNITROSO COMPOUNDS
Kirby, Gordon W.,Nazeer, Muhammad
, p. 6173 - 6174 (1988)
Transient, chiral α-hydroxyacylnitroso compounds (2), able to form intramolecular hydrogen bonds, react stereoselectively with cyclopentadiene and cyclohexa-1,3-diene; the cycloadduct (6) of the latter diene and the nitroso derivative of (S)-mandelic acid
