517906-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 517906-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,7,9,0 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 517906-87:
(8*5)+(7*1)+(6*7)+(5*9)+(4*0)+(3*6)+(2*8)+(1*7)=175
175 % 10 = 5
So 517906-87-5 is a valid CAS Registry Number.

Synthesis of polyketides via diastereoselective acetalization
Shepherd, Jennifer N.,Myles, David C.
, p. 1027 - 1030 (2007/10/03)
(Matrix presented) Diastereoselective acetalization of pseudo-C 2-symmetric 1,3,5-triol systems is a general strategy for the rapid generation of polyketides. The oxidative acetalization reaction shown above was studied under both kinetic and t
