Check Digit Verification of cas no
The CAS Registry Mumber 57543-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,4 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57543-58:
(7*5)+(6*7)+(5*5)+(4*4)+(3*3)+(2*5)+(1*8)=145
145 % 10 = 5
So 57543-58-5 is a valid CAS Registry Number.

Treatment of salicylaldehydes with acrylate derivatives in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) has been shown to afford both coumarin and chromene derivatives, and factors influencing the product distributions have been investigated.
