135626-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135626-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,2 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135626-22:
(8*1)+(7*3)+(6*5)+(5*6)+(4*2)+(3*6)+(2*2)+(1*2)=121
121 % 10 = 1
So 135626-22-1 is a valid CAS Registry Number.

A remarkable base-promoted methodology for the rapid construction of the (E)- and (Z)-γ-oxo-α,β-alkenoic ester skeletons from readily accessible vinyl propargylic alcohols through modified redox isomerization was uncovered. This approach manifested its hi
