193968-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193968-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,6 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193968-52:
(8*1)+(7*9)+(6*3)+(5*9)+(4*6)+(3*8)+(2*5)+(1*2)=194
194 % 10 = 4
So 193968-52-4 is a valid CAS Registry Number.

Synthesis of RNAse active site model systems using a steroid template
Oost, Thorsten,Kalesse, Markus
, p. 8421 - 8438 (2007/10/03)
An RNAse active site model system is described. The rigid steroid backbone is used as the template on which guanidinium and imidazole moieties, necessary for the transesterification/cleavage. are assembled. By changing the stereochemistry at C11 of 2, and
