55831-69-1 Usage
General Description
1,3-Butadiyne-1,4-diol is a chemical compound often utilized in organic synthesis due to its unique property of being a readily accessible C4-building block that contains two terminal functional groups. It has the molecular formula C4H4O2 and is also known as butadiyne-1,4-diol. This chemical is particularly used in the synthesis of various pharmaceuticals and bioactive compounds. Its high reactivity can be attributed to the presence of two acetylenic functional groups. In its pure form, it appears as an off-white or beige colored powder. Its use should be handled with extreme care due to its potential combustibility, reactivity and toxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 55831-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55831-69:
(7*5)+(6*5)+(5*8)+(4*3)+(3*1)+(2*6)+(1*9)=141
141 % 10 = 1
So 55831-69-1 is a valid CAS Registry Number.
