193622-63-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193622-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 193622-63:
(8*1)+(7*9)+(6*3)+(5*6)+(4*2)+(3*2)+(2*6)+(1*3)=148
148 % 10 = 8
So 193622-63-8 is a valid CAS Registry Number.

, p. 7589 - 7592 (2007/10/02)
The application of Negishi's cyclization methodology to the synthesis of (Z)-1-iodo-1,3-bis-exocyclic-dienes from acyclic precursors is described. This kind of compounds can be used for the preparation of conjugated systems such as the triene of vitamin D
