851763-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851763-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,7,6 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 851763-80:
(8*8)+(7*5)+(6*1)+(5*7)+(4*6)+(3*3)+(2*8)+(1*0)=189
189 % 10 = 9
So 851763-80-9 is a valid CAS Registry Number.

Stereoselective synthesis of 1,3-enynyltellurides via palladium catalysed cross-coupling reaction of (E)-α-iodovinyltellurides
Cai, Mingzhong,Chan, Junmin
, p. 840 - 842 (2007/10/03)
(E)-α-Iodovinyltellurides undergo a direct coupling reaction with terminal alkynes in the presence of [Pd(PPh3)4] and CuI catalysts in pyrrolidine at room temperature to give 1,3-enynyltellurides in good yields.
