934247-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 934247-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,2,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 934247-33:
(8*9)+(7*3)+(6*4)+(5*2)+(4*4)+(3*7)+(2*3)+(1*3)=173
173 % 10 = 3
So 934247-33-3 is a valid CAS Registry Number.

Synthetic studies toward cribrostatin IV: An intriguing epimerization
Chan, Collin,Danishefsky, Samuel J.
, p. 113 - 118 (2007/10/03)
Surprising effects of remote substituents on the relative rates of vinylogous Pictet-Spengler reaction versus epimerization through a Grigg like progression have been encountered (contrast cyclizations of 3 and 7). Deuterium labeling experiments have been
