Check Digit Verification of cas no

The CAS Registry Mumber 12100-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12100-65:
(7*1)+(6*2)+(5*1)+(4*0)+(3*0)+(2*6)+(1*5)=41
41 % 10 = 1
So 12100-65-1 is a valid CAS Registry Number.

Rapid Sonogashira cross-coupling of iodoferrocenes and the unexpected cyclo-oligomerization of 4-ethynylphenylthioacetate

Inkpen, Michael S.,White, Andrew J. P.,Albrecht, Tim,Long, Nicholas J.

, p. 5663 - 5665 (2013)

A systematic study into the Sonogashira cross-coupling of 1,1′-diiodoferrocene (fcI2) confirms that the Pd(0)-P( tBu)3 system provides a remarkable rate increase over Pd(0)-(PPh3)2. Attempts to couple 4- ethynylphenylthioacetate (2) with fcI2 instead produced a novel cyclic trimer of the former, from syn addition of S-Ac across CC.
