The chemical compound "(iso-C5H11)3SnC6H4-p-CHCH2" is a triorganotin compound, which is a type of organometallic compound that contains tin. Specifically, it has three iso-pentyl (iso-C5H11) groups attached to a tin atom, which is then bonded to a phenyl ring (C6H4) with a propargyl group (CHCH2) attached to the para position of the phenyl ring. (iso-C5H11)3SnC6H4-p-CHCH2 is known for its potential applications in various fields, such as in the synthesis of polymers, as a catalyst, or in the production of certain types of materials. It is also important to note that organotin compounds can have environmental and health implications due to their toxicity, and thus their use and disposal must be carefully managed.
The CAS Registry Mumber 1851-39-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1851-39: (6*1)+(5*8)+(4*5)+(3*1)+(2*3)+(1*9)=84 84 % 10 = 4 So 1851-39-4 is a valid CAS Registry Number.
