(4-chloro-benzyl)-succinic acid anhydride is a chemical compound with the molecular formula C11H9ClO3. It is an anhydride derivative of (4-chloro-benzyl)-succinic acid, which is formed by the removal of a water molecule from two molecules of the acid. (4-chloro-benzyl)-succinic acid anhydride is characterized by the presence of a 4-chloro-benzyl group attached to the succinic acid backbone. It is a white crystalline solid and is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. The anhydride form is often preferred in chemical reactions due to its increased reactivity compared to the parent acid.

1661-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1661-97-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1661-97:
(6*1)+(5*6)+(4*6)+(3*1)+(2*9)+(1*7)=88
88 % 10 = 8
So 1661-97-8 is a valid CAS Registry Number.
