Check Digit Verification of cas no
The CAS Registry Mumber 168850-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,8,5 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 168850-69:
(8*1)+(7*6)+(6*8)+(5*8)+(4*5)+(3*0)+(2*6)+(1*9)=179
179 % 10 = 9
So 168850-69-9 is a valid CAS Registry Number.

Synthetic Applications of Arenetricarbonylchromium(0) Complexes: the Synthesis of Polyfunctionalised Thiophenes
Loft, Michael S.,Mowlem, Timothy J.,Widdowson, David A.
, p. 97 - 104 (2007/10/02)
Lithiation of thiophenetricarbonylchromium(0) complexes with butyllithium occurs preferentially at C-2/5 but when these are blocked, 3/4 lithiation is facile.Combinations of a bulky silyl (i-Pr3Si or t-BuMe2Si) blocking group at C-2/5 and remote lithiation/electrophilic quench of C-3/4 followed by desilylation/lithiation/electrophilic quench allowed the synthesis of 2,3-, 2,3,5- and 2,3,4,5-polysubstituted thiophene complexes and their derived free thiophenes.
