It is a derivative of L-arabinopyranose, a type of sugar. 1,2:3,4-DI-O-ISOPROPYLIDENE-ALPHA-L-ARABINOPYRANOSE is used in organic synthesis as a protecting group for the hydroxyl group in carbohydrates. It is commonly used in the synthesis of complex natural products and pharmaceuticals, where the protection of certain hydroxyl groups is necessary to prevent unwanted reactions. 1,2:3,4-Di-O-isopropylidene-alpha-L-arabinopyranose is also used as a building block for the construction of other sugar derivatives and carbohydrate-based molecules in organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 27820-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27820-98:
(7*2)+(6*7)+(5*8)+(4*2)+(3*0)+(2*9)+(1*8)=130
130 % 10 = 0
So 27820-98-0 is a valid CAS Registry Number.

Tetrabutylammonium tribromide (TBATB): A mild and efficient catalyst for O-isopropylidenation of carbohydrates
Khan, Abu T.,Khan, Md. Musawwer,Adhikary, Anubendu
, p. 673 - 677 (2011)
A wide range of O-isopropylidene derivatives can be prepared from the sugars and their derivatives on reaction with acetone at room temperature by employing 2 mol % of tetrabutylammonium tribromide (TBATB) as a catalyst. Good yields, low catalyst loading, mild reaction conditions, and a non-aqueous workup procedure are some major advantages of this protocol.
