31101-37-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31101-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,0 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31101-37:
(7*3)+(6*1)+(5*1)+(4*0)+(3*1)+(2*3)+(1*7)=48
48 % 10 = 8
So 31101-37-8 is a valid CAS Registry Number.

Traceless solid-phase synthesis of 2-amino-5-alkylidene-thiazol-4-ones
Pulici, Maurizio,Quartieri, Francesca
, p. 2387 - 2391 (2007/10/03)
2-Amino-5-alkylidene-thiazol-4-ones bearing two diversity points are prepared by a solid-phase strategy exploiting rhodanine as the starting material. Rhodanine is first loaded on bromo-Wang resin, subjected to Knovenagel condensation with aldehydes, and cleaved off the resin in a traceless manner by means of an amine.
