The CAS Registry Mumber 138307-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,0 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138307-89:
(8*1)+(7*3)+(6*8)+(5*3)+(4*0)+(3*7)+(2*8)+(1*9)=138
138 % 10 = 8
So 138307-89-8 is a valid CAS Registry Number.

Higher order, mixed cyanocuprates derived from N-lithio-imidazole and pyrrole: New 'dummy' ligand alternatives in organocopper chemistry

Lipshutz,Fatheree,Hagen,Stevens

, p. 1041 - 1044 (1992)

Treatment of N-lithioimidazole or N-lithiopyrrole with CuCN followed by an organolithium leads to cuprates R(Imid)Cu(CN)Li2 and R(Pyrr)Cu(CN)Li2 which show 'higher order' reactivity relative to RCu(CN)Li.
