Check Digit Verification of cas no

The CAS Registry Mumber 1542233-49-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,2,3 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1542233-49:
(9*1)+(8*5)+(7*4)+(6*2)+(5*2)+(4*3)+(3*3)+(2*4)+(1*9)=137
137 % 10 = 7
So 1542233-49-7 is a valid CAS Registry Number.

Guanidine-catalyzed γ-selective morita-baylis-hillman reactions on α,γ-dialkyl-allenoates: Access to densely substituted heterocycles

Selig, Philipp,Turo?kin, Aleksej,Raven, William

, p. 2535 - 2539 (2013/12/04)

N-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD) was discovered as an excellent catalyst for the Morita-Baylis-?-Hillman reaction for previously hard-to-activate α,γ-dialkyl allenoate substrates. The obtained densely substituted allenic alcohols, which are generally inaccessible with other Lewis base catalysts, could be further converted into 2,5-dihydrofuran and 2H-pyran-2-one heterocyclic structures with challenging substitution patterns.
