121287-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121287-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,8 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121287-22:
(8*1)+(7*2)+(6*1)+(5*2)+(4*8)+(3*7)+(2*2)+(1*2)=97
97 % 10 = 7
So 121287-22-7 is a valid CAS Registry Number.

ALKYLATION OF ACTIVE HYDROGEN COMPOUNDS WITH ALLYLIC AND BENZYLIC ALCOHOLS UNDER CoCl2 CATALYSIS. A USEFUL SYNTHESIS OF GRIFOLIN
Marquet, J.,Moreno-Manas, M.
, p. 173 - 176 (2007/10/02)
CoCl2 is a useful catalyst for the condensation of allylic and benzylic alcohols with active hydrogen compounds.Under these neutral conditions orcinol and farnesol react to afford the antibiotic grifolin.
