Check Digit Verification of cas no
The CAS Registry Mumber 77085-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,8 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77085-57:
(7*7)+(6*7)+(5*0)+(4*8)+(3*5)+(2*5)+(1*7)=155
155 % 10 = 5
So 77085-57-5 is a valid CAS Registry Number.

5-Methoxy-2-furyl-carbinols (8) were converted by ZnCl2 catalysis into 3:1 mixture of 4-ylidene-butenolides (9) and 4-oxo-2-enoic acid methyl esters (10).The carbonium ion 12 is the key intermediate, the stability of which made the conversion very fast providing high yields.
