Check Digit Verification of cas no

The CAS Registry Mumber 874894-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,8,9 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 874894-28:
(8*8)+(7*7)+(6*4)+(5*8)+(4*9)+(3*4)+(2*2)+(1*8)=237
237 % 10 = 7
So 874894-28-7 is a valid CAS Registry Number.

Metathesis and metallotropy: A versatile combination for the synthesis of oligoenynes

Kim, Mansuk,Lee, Daesung

, p. 18024 - 18025 (2005)

We have demonstrated that the combined use of enyne metathesis and metallotropic [1,3]-shift of the corresponding alkynyl ruthenium carbenes is a powerful synthetic tool to construct oligoenynes. In this reaction, alkynyl carbene intermediates formed from an initial ring-closing metathesis reaction (RCM) undergo repetitive [1,3]-shifts and RCMs to give the final products. Linear poly-1,3-diynes containing repeating functionality of the type -[XCH2CCCCCH2]n- generated long-chain conjugated oligoenynes up to n = 5. Copyright
