212266-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212266-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,2,6 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212266-65:
(8*2)+(7*1)+(6*2)+(5*2)+(4*6)+(3*6)+(2*6)+(1*5)=104
104 % 10 = 4
So 212266-65-4 is a valid CAS Registry Number.

Wang, Qian,Sasaki, N. Andre,Potier, Pierre
, p. 5755 - 5758 (2007/10/03)
A new strategy for asymmetric synthesis of 2,4-disubstituted pyrrolidines is described, starting from readily available chiral building blocks 1 and (2R)-2,3-O-isopropylideneglycealdehyde (6).
