113705-05-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113705-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,7,0 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 113705-05:
(8*1)+(7*1)+(6*3)+(5*7)+(4*0)+(3*5)+(2*0)+(1*5)=88
88 % 10 = 8
So 113705-05-8 is a valid CAS Registry Number.

Mechanism of the Wittig Reaction: The Role of Substituents at Phosphorus
Vedejs, E.,Marth, C. F.
, p. 3948 - 3958 (2007/10/02)
The variation in Wittig reaction stereochemistry is attributed to a dominant kinetic control in nearly all cases.Formation of cis or trans oxaphosphetanes is the decisive step, and this occurs by an asynchronous cycloaddition.An interplay of 1, 2 and 1, 3
