87290-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87290-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87290-21:
(7*8)+(6*7)+(5*2)+(4*9)+(3*0)+(2*2)+(1*1)=149
149 % 10 = 9
So 87290-21-9 is a valid CAS Registry Number.

Pyridinium-, 2-methylpyridinium-, and 2,6-dimethylpyridinium-1-thioacylaminides (5-7) were prepared from the corresponding unsubstituted pyridinium-1-aminides and methyl dithiocarboxylates in fairly good yields.The alkylation reaction of 5-7 took place ex
