878191-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 878191-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,1,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 878191-45:
(8*8)+(7*7)+(6*8)+(5*1)+(4*9)+(3*1)+(2*4)+(1*5)=218
218 % 10 = 8
So 878191-45-8 is a valid CAS Registry Number.

Bi-3H-diazirin-3-yls as precursors of highly strained cycloalkynes
Al-Omari, Mohammad,Banert, Klaus,Hagedorn, Manfred
, p. 309 - 311 (2006)
(Chemical Equation Presented) No reagents and very mild conditions are required for the transformation of isolable precursors 3 into highly strained cycloalkynes 4 (cycloheptyne, cyclohexyne, norbornyne), which can be trapped by cycloaddition reactions.
