Check Digit Verification of cas no

The CAS Registry Mumber 97350-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,5 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 97350-99:
(7*9)+(6*7)+(5*3)+(4*5)+(3*0)+(2*9)+(1*9)=167
167 % 10 = 7
So 97350-99-7 is a valid CAS Registry Number.

Diastereofacial Selectivity in the Reaction of Allylic Organometallic Compounds with Imines. Stereoelectronic Effect of Imine Group

Yamamoto, Yoshinori,Komatsu, Toshiaki,Maruyama, Kazuhiro

, p. 3115 - 3121 (2007/10/02)

The diastereofacial selectivity in the reaction of crotyl organometallic compounds (4) (M = Li+, Mg, B, and Sn) with imines (3) is investigated.The reaction of ordinary imines produces the erythro isomer (5) predominantly regardless of the metal (M).With increase of the steric bulk of the R group or with aryl substituent in the R' group, the threo isomer (6) predominates in the reaction of crotyl-9-BBN.The ratio of erythro (11)/threo (12) in the reaction of pent-3-en-2-yl-9-BBN (9) is higher then the ratio of erythro (5)/threo (6) in the reaction of crotyl-9-BBN itself.On the basis of these observations, the transition-state geometry is discussed.
