Check Digit Verification of cas no

The CAS Registry Mumber 853688-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,6,8 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 853688-11:
(8*8)+(7*5)+(6*3)+(5*6)+(4*8)+(3*8)+(2*1)+(1*1)=206
206 % 10 = 6
So 853688-11-6 is a valid CAS Registry Number.

Palladium-catalyzed Suzuki-Miyaura coupling reactions involving β,β-dihaloenamides: Application to the synthesis of disubstituted ynamides

Couty, Sylvain,Barbazanges, Marion,Meyer, Christophe,Cossy, Janine

, p. 905 - 910 (2007/10/03)

β,β-Dihaloenamides can be successfully involved in palladium-catalyzed Suzuki-Miyaura coupling reactions. Whereas the resulting tri substituted (Z)-β-bromoenamides could participate in a second cross-coupling leading to β,β-disubstituted enamides, the (Z)-β-chloroenamides have been converted to disubstituted ynamides by an E2 elimination.
