Check Digit Verification of cas no

The CAS Registry Mumber 78638-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,3 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78638-84:
(7*7)+(6*8)+(5*6)+(4*3)+(3*8)+(2*8)+(1*4)=183
183 % 10 = 3
So 78638-84-3 is a valid CAS Registry Number.

Remote substituent effects on phenylchlorocarbene C-H insertion reactions

Moss, Robert A.,Yan, Shunqi

, p. 819 - 822 (1999)

Formula presented Phenylchlorocarbene inserts into the tertiary CH bonds of 1,3-dimethyladamantane and 1-X-adamantanes (X = H, OMe COOMe, Cl, CN). There is a good correlation between the relative rate constants for these insertions and the inductive subst

REACTIVITY AND SELECTIVITY IN INTERMOLECULAR INSERTION REACTIONS OF CHLOROPHENYLCARBENE

Doyle, Michael P.,Taunton, Jack,Oon, Su-Min,Liu, Michael T. H.,Soundararajan, N.,et. al.

, p. 5863 - 5866 (2007/10/02)

Reactivities for intermolecular C-H/Si-H/Sn-H insertion reactions of chlorophenylcarbene follow the order tri-n-butyltin hydride>>diphenylsilane>triethylsilane>>cumene>ethylbenzene>>toluene, and these reactions are competitive with addition to the double bond of α,β-unsaturated esters.
