Check Digit Verification of cas no
The CAS Registry Mumber 847862-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,8,6 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 847862-92:
(8*8)+(7*4)+(6*7)+(5*8)+(4*6)+(3*2)+(2*9)+(1*2)=224
224 % 10 = 4
So 847862-92-4 is a valid CAS Registry Number.

The first regioselective metalation and functionalization of unprotected 4-halobenzoic acids
Gohier, Frederic,Castanet, Anne-Sophie,Mortier, Jacques
, p. 1501 - 1504 (2005)
(Chemical Equation Presented) By treatment with s-BuLi, s-BuLi/TMEDA, or t-BuLi at ～-78°C, 4-fluoro- and 4-chlorobenzoic acids (1a,b) are metalated preferentially in the position adjacent to the carboxylate. A complete reversal in regioselectivity is observed for 1a when treated with LTMP; a sequential process involving a rapid intraaggregate lithiation through a quasi dianion complex "QUADAC" is postulated to explain the unusual reactivity of Me2S2 and I2.
