105480-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105480-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,8 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105480-02:
(8*1)+(7*0)+(6*5)+(5*4)+(4*8)+(3*0)+(2*0)+(1*2)=92
92 % 10 = 2
So 105480-02-2 is a valid CAS Registry Number.

REACTIVITY OF PENT-1-EN-4-YNES AND SYNTHESIS OF 2-SUBSTITUTED DERIVATIVES
Drewes, Siegfried E.,Slater-Kinghorn, Barbara J.
, p. 603 - 610 (2007/10/02)
The synthesis of some 2-substituted pent-1-en-4-ynes via an SN1 reaction is described.Using dicobalt octacarbonyl as protecting group, selective bromination of 1,5-diphenylpent-1en-4-yne is achieved.
