Naphthalene-1,5-disulfonic acid-2,7-diazide, also known as naphthalin-disulfonsaeure-(2,7)-diazid, is a chemical compound derived from naphthalene, a polycyclic aromatic hydrocarbon. Naphthalin-disulfonsaeure-(2,7)-diazid features a naphthalene core with two sulfonic acid groups at the 1 and 5 positions, and two azide groups at the 2 and 7 positions. It is a white crystalline solid that is soluble in water and has potential applications in the synthesis of dyes, pharmaceuticals, and other organic compounds. Due to the presence of azide groups, it should be handled with care, as azides can be explosive and toxic.

Check Digit Verification of cas no

The CAS Registry Mumber 7456-70-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,5 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7456-70:
(6*7)+(5*4)+(4*5)+(3*6)+(2*7)+(1*0)=114
114 % 10 = 4
So 7456-70-4 is a valid CAS Registry Number.
