Check Digit Verification of cas no

The CAS Registry Mumber 1387584-43-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,7,5,8 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1387584-43:
(9*1)+(8*3)+(7*8)+(6*7)+(5*5)+(4*8)+(3*4)+(2*4)+(1*3)=211
211 % 10 = 1
So 1387584-43-1 is a valid CAS Registry Number.

Consecutive Michael-claisen process for cyclohexane-1,3-dione derivative (CDD) synthesis from unsubstituted and substituted acetone 1

Sharma, Dharminder,Shil, Arun K.,Singh, Bikram,Das, Pralay

, p. 1199 - 1204 (2012)

A long-existing problem of cyclohexane-1,3-dione derivatives (CDD) synthesis from unreactive acetone through consecutive Michael-Claisen process was solved under this study. The practical applicability of this process was tested for a novel compound ethyl 3-(2,4-dioxocyclohexyl)propanoate for up to 20-gram scale. Furthermore, the scope of different acetone derivatives was investigated and resulted with similar consecutive Michael-Claisen process for CDD synthesis. The reaction exhibited remarkable regioselectivity in Michael addition followed by Claisen cyclization. In this process high substrate selectivity was observed for CDD synthesis following consecutive double-Michael-Claisen and Michael-Claisen cyclization. Georg Thieme Verlag Stuttgart · New York.
