Check Digit Verification of cas no

The CAS Registry Mumber 139025-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139025-72:
(8*1)+(7*3)+(6*9)+(5*0)+(4*2)+(3*5)+(2*7)+(1*2)=122
122 % 10 = 2
So 139025-72-2 is a valid CAS Registry Number.

NiCl2(PPh3)2-Zn Promoted Deallyloxycarbonylative Directed Aldol Reaction of Allyl β-Keto Carboxylates with Aldehydes th β-Hydroxy Ketones

Nokami, Junzo,Konishi, Haruhisa,Matsuura, Hiroyuki

, p. 2023 - 2026 (1991)

Regio- and chemospecific deallyloxycarbonylative aldol reaction of allyl (or -lic) α,α-disubstituted β-keto carboxylate with aldehyde was effectively promoted by Ni(0) (NiCl2(PPh3)2-Zn), in which the allyloxycarbonyl group (-COOCH2CH=CH2) was replaced to 1-hydroxyalkyl group (-CH(OH)R, R=alkyl, vinyl, aryl) under mild reaction conditions.
