Check Digit Verification of cas no

The CAS Registry Mumber 92052-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,5 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92052-59:
(7*9)+(6*2)+(5*0)+(4*5)+(3*2)+(2*5)+(1*9)=120
120 % 10 = 0
So 92052-59-0 is a valid CAS Registry Number.

Nitro-Olefin Trapping Reactions of Enolates In Situ Generated by Conjugate Addition Reaction: Short Syntheses of PGE1, 6-Oxo-PGE1, 6-Oxo-PGF1α, and PGI2

Tanaka, Toshio,Hazato, Atsuo,Bannai, Kiyoshi,Okamura, Noriaki,Sugiura, Satoshi,et al.

, p. 813 - 824 (1987)

The nitro-olefin trapping of the enolates in situ generated by conjugate addition of organocopper reagents to the chiral oxygenated cyclopentenone synthon, R-4, gives the three-component coupling products in a regiospecific manner.The intermediary nitronate anion 17 is further transformed into the nitro compound or 6-oxo-PGE1 (19) in a single pot.This coupling reaction is applicable to syntheses of naturally occurring prostaglandins such as PGE1, 6-oxo-PGF1α, and PGI2.
