Check Digit Verification of cas no

The CAS Registry Mumber 1450842-79-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,8,4 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1450842-79:
(9*1)+(8*4)+(7*5)+(6*0)+(5*8)+(4*4)+(3*2)+(2*7)+(1*9)=161
161 % 10 = 1
So 1450842-79-1 is a valid CAS Registry Number.

Formation of highly substituted tetrahydropyranones: Application to the total synthesis of cyanolide A

Tay, Gidget C.,Gesinski, Michael R.,Rychnovsky, Scott D.

, p. 4536 - 4539 (2013/09/24)

A new tetrahydropyranone synthesis has been developed that leads to cis-2,6-disubstituted 3,3-dimethyltetrahydropyran-4-one rings by condensation of an aldehyde and a hydroxy silyl enol ether. The reaction works with a variety of aldehydes to produce the tetrahydropyranone products in moderate to high yields. This new method was applied to the enantioselective synthesis of cyanolide A and its aglycone.
