Calculate Digit Verification of CAS Registry Number 133957-01:
(8*1)+(7*3)+(6*3)+(5*9)+(4*5)+(3*7)+(2*0)+(1*1)=134
134 % 10 = 4
So 133957-01-4 is a valid CAS Registry Number.

HIGH-PRESSURE CYCLOADDITION OF 1-METHOXY-1,3-BUTADIENE TO N,O-PROTECTED D-THREONINALS AND D-ALLO-THREONINALS

Golebiowski, A.,Jurczak, J.

, p. 1037 - 1044 (2007/10/02)

High-pressure cycloadditions of trans-1-methoxy-1,3-butadiene (3) to N,O-protected D-allo-threoninals (4) and D-threoninals (8) were studied.In all cases, 5,6-syn-adducts were the major products.The results are explained by α-chelation with Eu(fod)3
