Check Digit Verification of cas no

The CAS Registry Mumber 499767-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,7,6 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 499767-79:
(8*4)+(7*9)+(6*9)+(5*7)+(4*6)+(3*7)+(2*7)+(1*9)=252
252 % 10 = 2
So 499767-79-2 is a valid CAS Registry Number.

Facile transformation of 2-azetidinones to unsaturated ketones: Application to the formal synthesis of sphingosine and phytosphingosine

Lee, Hyeon Kyu,Kim, Eun-Kyung,Pak, Chwang Siek

, p. 9641 - 9644 (2007/10/03)

2-Azetidinones were smoothly transformed to unsaturated ketones through the ring opening of activated 2-azetidinone by phosphonate stabilized carbanion and subsequent Horner-Wadsworth-Emmons olefination of the resulting β-ketophosphonates with aldehydes.
