Check Digit Verification of cas no
The CAS Registry Mumber 284493-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,4,9 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 284493-65:
(8*2)+(7*8)+(6*4)+(5*4)+(4*9)+(3*3)+(2*6)+(1*5)=178
178 % 10 = 8
So 284493-65-8 is a valid CAS Registry Number.

2H-Pyrans are constructed on a 1-oxa- or 1-azacyclohexane-2,4-dione core via Knoevenagel condensation with enals followed by 6π.electrocyclization, which are readily catalyzed with ethylenediammonium diacetate. This formal [3 + 3] strategy constitutes CO
