Check Digit Verification of cas no

The CAS Registry Mumber 158299-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,9 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 158299-82:
(8*1)+(7*5)+(6*8)+(5*2)+(4*9)+(3*9)+(2*8)+(1*2)=182
182 % 10 = 2
So 158299-82-2 is a valid CAS Registry Number.

(Cyanomethylene)phosphoranes as Novel Carbonyl 1,1-Dipole Synthons: An Efficient Synthesis of α-Keto Acids, Esters, and Amides

Wasserman, Harry H.,Ho, Wen-Bin

, p. 4364 - 4366 (1994)

Carboxylic acids react with (cyanomethylene)triphenylphosphorane in the presence of EDCI to form cyano keto phosphoranes.The resulting ylides may then be oxidatively cleaved with ozone to form α,β-diketonitriles.These highly electrophilic products may then be converted in situ to α-keto acids, esters, and amides.
