173557-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173557-77-2 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, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 173557-77:
(8*1)+(7*7)+(6*3)+(5*5)+(4*5)+(3*7)+(2*7)+(1*7)=162
162 % 10 = 2
So 173557-77-2 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 (1995)
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.
