Check Digit Verification of cas no

The CAS Registry Mumber 35281-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,2,8 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 35281-62:
(7*3)+(6*5)+(5*2)+(4*8)+(3*1)+(2*6)+(1*2)=110
110 % 10 = 0
So 35281-62-0 is a valid CAS Registry Number.

Copper-Catalyzed Direct and Stereoselective Synthesis of Conjugated Enynes from α-Allenols

Sai, Masahiro,Matsubara, Seijiro

supporting information, p. 39 - 43 (2018/11/23)

A novel strategy for the stereoselective synthesis of conjugated enynes directly from α-allenols has been developed. The reaction proceeds with perfect E-selectivity and exhibits high functional group compatibility. This catalytic system can also be applied to the stereoselective synthesis of conjugated dienynes and enediynes. (Figure presented.).
