136994-95-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136994-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,9 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136994-95:
(8*1)+(7*3)+(6*6)+(5*9)+(4*9)+(3*4)+(2*9)+(1*5)=181
181 % 10 = 1
So 136994-95-1 is a valid CAS Registry Number.

One-pot synthesis of 1-aryl-1 H,3 H-thiazolo[3,4-a[benzimidazoles using magnetite-linked sulfonic acid as catalyst
Wu, Liqiang,Wang, Xiao
, p. 1851 - 1857 (2015/10/29)
A series of 1-aryl-1H,3H-thiazolo[3,4-a]benzimidazole derivatives have been synthesized via the three-component reaction of o-phenylenediamine, aromatic aldehydes, and 2-mercaptoacetic acid, catalyzed by magnetite-linked sulfonic acid. This method has the
