Check Digit Verification of cas no

The CAS Registry Mumber 163877-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,7 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 163877-65:
(8*1)+(7*6)+(6*3)+(5*8)+(4*7)+(3*7)+(2*6)+(1*5)=174
174 % 10 = 4
So 163877-65-4 is a valid CAS Registry Number.

A study of Pd(II) Cl2/CuCl catalysed Wacker reaction for the deprotection of prop-2-enyl and prop-1-enyl ethers

Mereyala, Hari Babu,Lingannagaru, Sarita Reddy

, p. 17501 - 17512 (2007/10/03)

Pd(II)Cl2 (1 mole equivalent)/CuCl/DMF-H2O/O2/2h catalysed oxidation of various prop-2-enyl ethers 1a-12a is reported to result in the formation of Wacker ketones 1b,3b,5b,6b,9b,11b,12b (12-51%), hydrolysis products 2c,4c-7c,9c-12c (12-43%) and η2-vinyl complexes of palladium chloride 2c,4c,7c,8c (52-94%) respectively. The corresponding prop-1-enyl ethers 2e,4e-12e under similar conditions react with a catalytic amount of Pd(II)Cl2 (0.2 mole equivalent) rapidly (15-20 min.) to give exclusively hydroxy compounds 2c,4c-12c respectively in good yields (75-97%).
