137447-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137447-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137447-97:
(8*1)+(7*3)+(6*7)+(5*4)+(4*4)+(3*7)+(2*9)+(1*7)=153
153 % 10 = 3
So 137447-97-3 is a valid CAS Registry Number.

New Chiral Solvating Agents: 1,5-Benzothiazepines
Giordano, Claudio,Restelli, Angelo
, p. 785 - 788 (1991)
For the first time it is reported that 1,5-benzothiazepines (1a-e) (Figure 1) behave as effective chiral solvating agents (CSA) for NMR enantiomeric excess (ee) determination of different classes of compounds such as α-arylalkanoic acids, α-hydroxy acids,
