Check Digit Verification of cas no

The CAS Registry Mumber 82420-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,2 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82420-07:
(7*8)+(6*2)+(5*4)+(4*2)+(3*0)+(2*0)+(1*7)=103
103 % 10 = 3
So 82420-07-3 is a valid CAS Registry Number.

Reactions Between 4-Hydroxy-6-methyl-2-pyrone and Aldehydes Both in the Absence and the Presence of Added Thiols

de March, P.,Moreno-Manas, M.,Pi, R.,Trius, A.

, p. 335 - 336 (2007/10/02)

Aldehydes react with 4-hydroxy-6-methyl-2-pyrone, 2, under Knoevenagel conditions to afford very electrophilic intermediates, wich can be trapped by more 2 or thiols to give dilactones 3 or monolactones 4.
