Check Digit Verification of cas no
The CAS Registry Mumber 1846-68-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1846-68:
(6*1)+(5*8)+(4*4)+(3*6)+(2*6)+(1*8)=100
100 % 10 = 0
So 1846-68-0 is a valid CAS Registry Number.

A palladium-catalyzed oxidative borylation reaction of conjugated enynones is developed. This reaction represents a new method for the synthesis of furyl-substituted alkenylboronates. The reaction works well with a series of conjugated enynones. Boryl migratory insertion of the palladium carbene intermediate is proposed as the key step in these transformations.
