Check Digit Verification of cas no

The CAS Registry Mumber 193021-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,0,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193021-17:
(8*1)+(7*9)+(6*3)+(5*0)+(4*2)+(3*1)+(2*1)+(1*7)=109
109 % 10 = 9
So 193021-17-9 is a valid CAS Registry Number.

Dephosphonylation of β-carbonyl phosphonates

Lee, Shi Yong,Lee, Chi-Wan,Oh, Dong Young

, p. 7017 - 7022 (1999)

A new methodology has been developed for the P-C bond cleavage of β- carbonyl phosphonates. The α,α-disubstituted β-keto phosphonates and the α-carbamoyl phosphonates have been shown to undergo dephosphonylation by reaction of their lithium enolate with LiAlH4, followed by quenching with aqueous H2SO4, affording regioselectively α,α-disubstituted ketone and α-substituted and α,α-disubstituted secondary amides.
