129694-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129694-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,9 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129694-13:
(8*1)+(7*2)+(6*9)+(5*6)+(4*9)+(3*4)+(2*1)+(1*3)=159
159 % 10 = 9
So 129694-13-9 is a valid CAS Registry Number.

Additional flexibility solves the leaving group problem in cyclodextrin acylation
Breslow, Ronald,Chung, Shin
, p. 631 - 634 (2007/10/02)
The rate of acylation of β-cyclodextrin by substituted phenyl esters of adamantanepropiolic acid shows a normal dependance on the basicity of the leaving group. This shows that the abnormal behavior in acylation by ferroceneacrylate esters can be solved w
