Check Digit Verification of cas no

The CAS Registry Mumber 156994-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,9 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156994-84:
(8*1)+(7*5)+(6*6)+(5*9)+(4*9)+(3*4)+(2*8)+(1*4)=192
192 % 10 = 2
So 156994-84-2 is a valid CAS Registry Number.

Tin/mercury exchange in 1,2-distannyl-1-alkenes and 1-silyl-2-stannyl-1-alkenes

Mitchell, T. N.,Kowall, B.

, p. 39 - 42 (2007/10/02)

1,2-Bis(chloromercuri)alkenes, 1-trimethylsilyl-2-chloromercuri-alkenes and 1-trimethylsilyl-2-organomercurialkenes can be readily made by transmetallation of the corresponding trimethyltin compounds with HgCl2 and RHgCl; their structures have been confirmed by multinuclear NMR data.The new compounds are expected to have a large synthetic potential involving lithium/mercury exchange, and subsequent reaction with electrophilic reagents.Key words: Mercury; Nuclear magnetic resonance; Tin; Silicon
