Check Digit Verification of cas no
The CAS Registry Mumber 63737-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,7,3 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 63737-71:
(7*6)+(6*3)+(5*7)+(4*3)+(3*7)+(2*7)+(1*1)=143
143 % 10 = 3
So 63737-71-3 is a valid CAS Registry Number.

Carbanion-Accelerated Claisen Rearrangements. 8. Phosphonamide Anion-Stabilizing Groups
Denmark, Scott E.,Stadler, Heinz,Dorow, Roberta L.,Kim, Jung-Ho

The utility of various phosphonamide groups has been examined in the context of the carbanion-accelerated Claisen rearrangement (CACR).An extensive survey has identified the N,N'-dibenzyl-1,3,2-diazaphospholidine group 11 to be optimal in the ease of construction of the CACR precursors and the facility and stereoselectivity of the rearrangement.Using n-butyllithium as the base, the phosphonamides rearranged readily at -20 deg C with complete regioselectivity and in good yield (74-79percent).The phosphonates also showed a high level of diastereoselectivity (>95percent de) but the yield from the (Z)-2-butenyl precursor (anti product) was only 45percent.A chiral N,N'-dibenzyl-1,3,2-diazaphospholidine 12 derived from trans-1,2-cyclohexanediamine was examined.Although the CACR proceeded very cleanly (71-85percent) and with high internal selectivity (94percent de), the relative asymmetric induction was poor (16-20percent de).This was also the case for a chiral N,N'-dibenzyl-1,3,2-diazaphosphorinane 15 derived from (R,R)-1,3-diphenyl-1,3-propanediamine and N,N'-dibenzyl-1,3,2-diazaphosphepine 16 derived from 6,6'-dimethyl-2,2'-diaminobiphenyl.The characteristic features of the CACR were compared with the aryl sulfone and phosphonate versions.
