General Description
3,4-Dihydro-1,2-naphthalenedicarboxylic Anhydride, also known as 1,2,3,4-Tetrahydro-1,2-naphthalenedicarboxylic anhydride, is a chemical compound primarily used in the production of polyesters, resins or plasticizers in the chemical industry. It appears as a white to light-yellow crystalline powder and is slightly soluble in water. It must be handled with care as it may cause skin and eye irritation, and in some cases, an allergic skin reaction. Additionally, it is harmful if ingested or inhaled, highlighting the need for protective equipment and proper ventilation when handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 37845-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,4 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37845-14:
(7*3)+(6*7)+(5*8)+(4*4)+(3*5)+(2*1)+(1*4)=140
140 % 10 = 0
So 37845-14-0 is a valid CAS Registry Number.
