1402222-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1402222-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,2,2 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1402222-50:
(9*1)+(8*4)+(7*0)+(6*2)+(5*2)+(4*2)+(3*2)+(2*5)+(1*0)=87
87 % 10 = 7
So 1402222-50-7 is a valid CAS Registry Number.

In presence of triethylamine, the reaction of substituted 2-aroyl-hydrazinecarbothioamides with 1,4-Diphenyl-but-2-yne-1,4-dione afforded novel furo[3,4-d]-1,3-thiazoles in good yield. The reaction mechanism suggests that the second molecule of 1,4-Diphen
