119385-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119385-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119385-23:
(8*1)+(7*1)+(6*9)+(5*3)+(4*8)+(3*5)+(2*2)+(1*3)=138
138 % 10 = 8
So 119385-23-8 is a valid CAS Registry Number.

Acid-promoted prins cyclizations of enol ethers to form tetrahydropyrans
Hart, David J.,Bennett, Chad E.
, p. 1499 - 1502 (2007/10/03)
(Matrix presented) Trifluoroacetic acid efficiently catalyzes Prins cyclizations of enol ethers 8 to provide tetrahydropyrans 9 and 10. These tetrahydropyrans are isolated with combined yields of 42-85% and stereoselectivities at C4 ranging fro
