74253-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74253-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,5 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74253-00:
(7*7)+(6*4)+(5*2)+(4*5)+(3*3)+(2*0)+(1*0)=112
112 % 10 = 2
So 74253-00-2 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESES BASED ON 1,3-OXATHIANES. 1. SCOPE OF THE REACTION.
Eliel,Morris-Natschke
, p. 2937 - 2942 (2007/10/02)
The stereoselectivity of the reactions of 2-acyl- and 2-aroyl-4,4,6-trimethyl-1,3-oxathianes and -4,6,6-trimethyl-1,3-oxathianes with organometallic reagents has been studied as a function of the following reaction variables: substitution pattern (4,4,6 o
