Check Digit Verification of cas no
The CAS Registry Mumber 148826-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,8,2 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 148826-21:
(8*1)+(7*4)+(6*8)+(5*8)+(4*2)+(3*6)+(2*2)+(1*1)=155
155 % 10 = 5
So 148826-21-5 is a valid CAS Registry Number.

, p. 3094 - 3096 (1991)
The reaction of 4,5-epoxy-2-hexenoate 2 and various nucleophiles in the presence of BF3.Et2O predominantly gave the (4,5)-5-hydroxy-4-substituted compounds. Among them, (±)-(4,5)-anti-5-hydroxy-4-thiophenoxy ester 17 was enantioselec
