857085-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857085-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,0,8 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 857085-93:
(8*8)+(7*5)+(6*7)+(5*0)+(4*8)+(3*5)+(2*9)+(1*3)=209
209 % 10 = 9
So 857085-93-9 is a valid CAS Registry Number.

Enynylation of 2-iodo-4-(phenylchalcogenyl)-1-butenes via intramolecular chelation: Approach to the synthesis of conjugated dienynes or trienynes

Shi, Min,Liu, Le-Ping,Tang, Jie

, p. 3085 - 3088 (2007/10/03)

(Chemical Equation Presented) 2-Iodo-4-(phenylchalcogenyl)-1 -butenes 3 and 4, which are derived from methylenecyclopropanes 1, can be enynylated with alkynes catalyzed by Pd(OAc)2 to give conjugated dienynes 5 and 6 in the absence of any phosp
