The chemical "2H-Pyran-4-ol, 2-[(1E,4S,6R,7E)-4,6-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-8-phenyl-1,7-octadienyl]-3,4-dihydro-, (2S)-" is a complex organic compound with a unique structure. It features a pyran-4-ol core, which is a type of heterocyclic compound with a six-membered ring containing one oxygen atom. The compound has a 1,7-octadienyl side chain with a phenyl group at the eighth carbon, and the 4 and 6 carbons of this side chain are each bonded to a dimethylsilyl ether group, which is a protecting group commonly used in organic synthesis. The (2S)- configuration indicates that the compound has a specific chirality at the second carbon. 2H-Pyran-4-ol, 2-[(1E,4S,6R,7E)-4,6-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]-8-phenyl- 1,7-octadienyl]-3,4-dihydro-, (2S)- is likely used in advanced chemical synthesis, particularly in the protection of functional groups or as an intermediate in the preparation of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 678970-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,9,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 678970-62:
(8*6)+(7*7)+(6*8)+(5*9)+(4*7)+(3*0)+(2*6)+(1*2)=232
232 % 10 = 2
So 678970-62-2 is a valid CAS Registry Number.
