222297-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222297-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,2,9 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 222297-54:
(8*2)+(7*2)+(6*2)+(5*2)+(4*9)+(3*7)+(2*5)+(1*4)=123
123 % 10 = 3
So 222297-54-3 is a valid CAS Registry Number.

Syntheses of C2-symmetric vicinal diamines derived from tartaric acid
Scheurer, Andreas,Mosset, Paul,Saalfrank, Rolf W.
, p. 3559 - 3570 (2007/10/03)
C2-symmetric vicinal diamines 3b-f, derived from L-tartaric acid, with increasingly bulky terminal ether functionalities were prepared using two distinct sequences. Diamines 3b,c were obtained from the corresponding vicinal diols 4b,c, while di
