Check Digit Verification of cas no

The CAS Registry Mumber 1009105-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,9,1,0 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1009105-59:
(9*1)+(8*0)+(7*0)+(6*9)+(5*1)+(4*0)+(3*5)+(2*5)+(1*9)=102
102 % 10 = 2
So 1009105-59-2 is a valid CAS Registry Number.

Imidazol-2-and-4-ylidene by decarboxylation. Studies on the cross-conjugated mesomeric betaine-alkaloid norzooanemonine and its pseudo-cross-conjugated isomer

Schmidt, Andreas,Beutler, Ariane,Albrecht, Marcel,Snovydovych, Bohdan,Ramirez, Francisco Javier

, p. 287 - 295 (2008/09/21)

1,3-Dimethylimidazolium-2-carboxylate and -4-carboxylate (norzooanemonine), which belong to two distinct classes of heterocyclic mesomeric betaines, undergo thermal decarboxylations to the N-heterocyclic carbenes imidazol-2-ylidene and imidazol-4-ylidene, respectively. These carbenes can be detected by ESI mass spectrometry and can be trapped by isocyanates to imidazolium-amidates, the structure of which was proved by independent syntheses. We performed calculations to characterize the different types of conjugation in the imidazolium-carboxylates. This journal is The Royal Society of Chemistry.
