Check Digit Verification of cas no

The CAS Registry Mumber 1129987-01-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,9,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1129987-01:
(9*1)+(8*1)+(7*2)+(6*9)+(5*9)+(4*8)+(3*7)+(2*0)+(1*1)=184
184 % 10 = 4
So 1129987-01-4 is a valid CAS Registry Number.

Organocatalysis by bimacrocyclic NHCs: Unexpected formation of a cyclic hemiacetal instead of a γ-butyrolactone

Winkelmann, Ole,Naether, Christian,Luening, Ulrich

, p. 553 - 556 (2009)

Two bimacrocyclic imidazolinium salts of different size, precursors to respective NHCs (N-heterocyclic carbenes), were tested as precatalysts in the reaction of aromatic aldehydes or ketones with enals. The expected lactones were produced in most cases, b
