Check Digit Verification of cas no

The CAS Registry Mumber 99121-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99121-25:
(7*9)+(6*9)+(5*1)+(4*2)+(3*1)+(2*2)+(1*5)=142
142 % 10 = 2
So 99121-25-2 is a valid CAS Registry Number.

Preparation of unsymmetrical ketones from tosylhydrazones and aromatic aldehydes via formyl C-H bond insertion

Allwood, Daniel M.,Blakemore, David C.,Ley, Steven V.

supporting information, p. 3064 - 3067 (2014/06/23)

Preparation of ketones by insertion of diazo compounds into the formyl C-H bond of an aldehyde is an attractive procedure, but use of structurally diverse diazo compounds is hampered by preparation and safety issues. A convenient procedure for the synthesis of unsymmetrical ketones from bench-stable tosylhydrazones and aryl aldehydes is reported. The procedure can be performed in one pot from the parent carbonyl compound and needs only a base, with no additional promoters being required.
