Check Digit Verification of cas no

The CAS Registry Mumber 869790-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,7,9 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 869790-50:
(8*8)+(7*6)+(6*9)+(5*7)+(4*9)+(3*0)+(2*5)+(1*0)=241
241 % 10 = 1
So 869790-50-1 is a valid CAS Registry Number.

Intramolecular carbonylation reactions with recyclable palladium-complexed dendrimers on silica: Synthesis of oxygen, nitrogen, or sulfur-containing medium ring fused heterocycles

Lu, Shui-Ming,Alper, Howard

, p. 14776 - 14784 (2007/10/03)

Palladium-complexed dendrimers supported on silica were evaluated as catalysts for intramolecular carbonylation reactions. The results showed that dendritic catalysts display high activity, affording oxygen, nitrogen, or sulfur-containing seven- or eight-membered ring fused heterocycles in excellent yields. Moreover, these catalysts have competitive advantages in that they can be easily recovered by simple filtration in air and reused for up to eight cycles with only a slight loss of activity.
