693833-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 693833-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,3,8,3 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 693833-41:
(8*6)+(7*9)+(6*3)+(5*8)+(4*3)+(3*3)+(2*4)+(1*1)=199
199 % 10 = 9
So 693833-41-9 is a valid CAS Registry Number.

An iterative approach to three fragments of ionomycin
Spino, Claude,Allan, Martin
, p. 177 - 184 (2007/10/03)
The SN2′ displacement of menthone-derived allylic carbonates with cuprate reagents occurs with high diastereoselectivity. This method can be used in an iterative fashion to construct stereocenters bearing a 1,3-relationship in a carbon chain. E
