Check Digit Verification of cas no

The CAS Registry Mumber 67915-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,1 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67915-82:
(7*6)+(6*7)+(5*9)+(4*1)+(3*5)+(2*8)+(1*2)=166
166 % 10 = 6
So 67915-82-6 is a valid CAS Registry Number.

ELECTROCHEMICAL SYNTHESIS OF SELENO AND TELLURO DERIVATIVES IN MeCN

Degrand, Chantal,Prest, Rita,Nour, Mohamed

, p. 201 - 210 (2007/10/02)

Large-scale electrolysis with concurrent sonication in MeCN allows for the synthesis of a large variety of seleno and telluro derivatives.Aliphatic chalcogenides REER or RER (E = Se, Te) can be prepared by reduction of E powder to E2(2-) or E(2-), followed by addition of an alkyl halide RX.Depending upon R, substitution can compete with homogeneous electron or H+ transfers.RE+ can be prepared by anodic oxidation of REER, and trapped by nucleophiles and olefins.The synthesis of aromatic chalcogenides ArEAr'can be carried out by electrochemically inducedSRN1 substitution.The yields are improved by redox catalysis.Under such conditions, the synthesis of PhEAr (Ar = NCC6H4, PhCOC6H4) proceeds in good yields.ArEEAr and ArEAr can be prepared by cathodic reduction of PhEAr.
