Check Digit Verification of cas no

The CAS Registry Mumber 1155956-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,9,5 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1155956-75:
(9*1)+(8*1)+(7*5)+(6*5)+(5*9)+(4*5)+(3*6)+(2*7)+(1*5)=184
184 % 10 = 4
So 1155956-75-4 is a valid CAS Registry Number.

Lewis Acid Catalyzed [3+3] Annulation of Donor–Acceptor Cyclopropanes with γ-Hydroxyenones: Access to Highly Functionalized Tetrahydropyrans

Mondal, Keshab,Pan, Subhas Chandra

, p. 534 - 537 (2017/02/05)

Donor–acceptor cyclopropanes were engaged in a [3+3]-annulation reaction with γ-hydroxyenones. Sc(OTf)3was found to be the best catalyst, and 2,4,4,5-tetrasubstituted tetrahydropyran products were obtained in good yields under mild reaction con
