Check Digit Verification of cas no

The CAS Registry Mumber 82423-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,2 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82423-73:
(7*8)+(6*2)+(5*4)+(4*2)+(3*3)+(2*7)+(1*3)=122
122 % 10 = 2
So 82423-73-2 is a valid CAS Registry Number.

Keten Silyl Acetal Chemistry; Simple Synthesis of Methyl Jasmonate and Related Compounds by Utilising Keten Methyl Dimethyl-t-butylsilyl Acetal

, p. 1099 - 1104 (2007/10/02)

Conjugate addition of keten silyl acetals to α,β-unsaturated carbonyl compounds in acetonitrile gave a quantitative yield of the corresponding methyl (3-trialkylsiloxyalk-2-enyl)acetates; subsequent site-specific electrophilic substitution yielded the corresponding 2-substituted 3-(alkoxycarbonylmethyl)alkanones.These novel addition and sequential alkylation reactions could be applied to a simple synthesis of methyl jasmonate, methyl didehydrojasmonate, and methyl dihydrojasmonate.
