173557-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173557-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173557-86:
(8*1)+(7*7)+(6*3)+(5*5)+(4*5)+(3*7)+(2*8)+(1*6)=163
163 % 10 = 3
So 173557-86-3 is a valid CAS Registry Number.

Mechanistic studies on thiaminase I. 1. The stereochemical course of the reaction
Nicewonger,Rammelsberg,Costello,Begley
, p. 512 - 518 (2007/10/03)
Thiaminase I catalyzes the displacement of the thiazole moiety of thiamin by a wide variety of nucleophiles. In this paper, we demonstrate that this reaction proceeds with overall retention of stereochemistry.
